1、 Product Introduction

YST109B-HP880 型Online pH analyzer(hereinafter referred to as "this instrument") mainly consists of sensors, transmitters, and auxiliary components (such as cleaning devices, temperature compensation probes). The sensor directly contacts the liquid to be measured and converts the pH value into an electrical signal; After amplifying and processing the signal, the transmitter outputs data in digital or analog form; Some configurations also have data storage, remote communication, and alarm functions, which can be linked with the central control system to achieve unmanned monitoring.

Its core value lies in breaking free from the limitations of manual laboratory testing, eliminating the need for frequent manual sampling, and being able to continuously monitor the pH changes of target liquids 24 hours a day, especially suitable for scenarios that require long-term and continuous control of water quality acidity and alkalinity.

2、 Advantages and Characteristics

Strong real-time performanceThe data collection interval can be flexibly set (with a minimum of seconds), providing real-time feedback on pH fluctuations to avoid water quality exceeding standards or process abnormalities caused by delayed detection.

High degree of automationSupport automatic temperature compensation (to offset the impact of temperature on pH measurement), automatic cleaning (to reduce sensor contamination and extend service life), and reduce manual maintenance costs.

Good environmental adaptabilitySensor housings are often made of corrosion-resistant materials (such as polytetrafluoroethylene), which can adapt to complex and harsh liquid environments such as sewage treatment plants and chemical wastewater, and operate stably.

data traceabilityEquipped with data storage and export functions, some configurations can be connected to cloud platforms, making it convenient for users to trace historical data and meet the needs of environmental monitoring and process review.

Match the characteristics of the measured mediumIf the liquid to be tested contains high suspended solids (such as wastewater from aeration tanks in sewage treatment plants), choose our YST109B-HP880 model with automatic cleaning function to avoid sensor blockage; If it is a highly corrosive liquid (such as chemical wastewater), it is necessary to confirm the corrosion resistance of the sensor material and prioritize the configuration of PTFE shell.

Adapt to installation environmentOutdoor installation (such as river water quality monitoring) should choose the YST109B-HP880 configuration with waterproof and sun protection design, and the protection level should not be lower than IP65; Pipeline monitoring requires the selection of flow or pipeline sensors with corresponding sizes based on the diameter of the pipeline.

Meet data requirementsIf remote monitoring is required (such as smart rural water management), the YST109B-HP880 configuration that supports 4G/5G or Internet of Things (IoT) communication should be selected; If it is necessary to interface with the factory control system, it is necessary to confirm that the output signal is compatible with the control system (such as RS485 protocol).

Consider maintaining conveniencePrioritize the YST109B-HP880 configuration with convenient sensor replacement and simple calibration process, especially for remote scenarios such as rural water management in mountainous areas, which can reduce the difficulty of later maintenance.

5、 Application industry

1. Sewage treatment plant

Monitoring process: water inlet (to determine the acidity/alkalinity strength of sewage and provide a basis for pre-treatment dosing), aeration tank (to regulate pH value to ensure microbial activity and improve degradation efficiency), water outlet (to ensure pH value meets discharge standards and avoid polluting the receiving water body). Our YST109B-HP880 instrument can stably adapt to these processes.

2. Water treatment plant/water purification plant

Monitoring process: Raw water (monitoring the pH fluctuations of natural water sources, such as the impact of acidic substances flowing in during the rainy season), dosing process (such as controlling the pH value during coagulation and disinfection to improve the effectiveness of chemicals), factory water (ensuring that the pH value of tap water is within the range of drinking water hygiene standards, avoiding stimulation to the human body or corrosion of the pipeline network). The YST109B-HP880 instrument can provide continuous monitoring support.

3. Municipal water supply network

Monitoring process: At the end of the pipeline network (such as secondary water supply points in residential areas) and key pipeline nodes, real-time monitoring of pH value changes is carried out to determine whether there is corrosion in the pipeline network (such as metal leaching caused by low pH), ensuring the safety of terminal water supply. The YST109B-HP880 instrument can meet the needs of pipeline scene monitoring.

4. Environmentally friendly water treatment

Monitoring process: Industrial wastewater pretreatment stations (such as centralized sewage treatment centers in industrial parks), surface water bodies (such as lakes and reservoirs), assisting environmental protection departments in monitoring water quality, timely detecting pH abnormalities (such as illegal discharge of alkaline wastewater by enterprises), preventing water acidification or alkalization. The YST109B-HP880 instrument can play a monitoring role.

5. Thermal heating

Monitoring link: The heating circulating water system controls the pH value of the circulating water to 8.5~10.5 (to avoid corrosion of pipelines by acidic water and scaling by alkaline water), reduces the risk of pipeline leakage, and extends the service life of the heating system. The YST109B-HP880 instrument can be adapted to the monitoring scenario of circulating water.

6. Hospital wastewater treatment

Monitoring process: Wastewater pretreatment tank (hospital wastewater contains disinfectants and chemicals, with large pH fluctuations), effluent after disinfection to ensure that the pH of the treated wastewater meets the standard for discharge, and to prevent disinfectants (such as sodium hypochlorite) from failing at unsuitable pH. The YST109B-HP880 instrument can stably monitor such scenarios.

7. Chemical wastewater treatment

Monitoring process: production workshop drainage outlet, wastewater regulation tank, neutralization reaction tank, precise control of neutralizing agent (such as acid/alkali solution) dosage, reducing treatment costs while avoiding subsequent process failures caused by neutralization. The YST109B-HP880 instrument can meet the monitoring needs of chemical wastewater.

8. River water quality monitoring

Monitoring process: Real time monitoring of pH values near river sections and discharge outlets to assist in determining whether water bodies are polluted (such as sudden drops/increases in pH caused by industrial wastewater discharge), providing data support for river management. The YST109B-HP880 instrument can be adapted to outdoor river monitoring scenarios.

9. Smart rural water management

Monitoring process: Rural centralized water supply stations (such as well water and purified water from reservoirs) and decentralized sewage treatment facilities (such as household sewage treatment tanks) can achieve unmanned supervision of rural water affairs through remote data transmission. The YST109B-HP880 instrument can support rural water affairs monitoring.

6、 Technology Trends

intelligent upgradeOn the basis of the YST109B-HP880 model, Dalian Yister is promoting intelligent upgrades and combining AI algorithms to achieve "predictive maintenance". By analyzing the usage time and data fluctuation patterns of sensors, we can provide early warnings of sensor aging, pollution, and other issues, reducing sudden failures.

IoT convergenceIn the future, more derivative configurations of YST109B-HP880 that support access to cloud platforms will be launched. Users can view real-time pH data from multiple sites through a mobile app or computer, achieving centralized monitoring across regions and scenarios (such as unified management of multiple rural water stations in a certain region).

modular designWe plan to optimize the structure of the YST109B-HP880 model by modularizing the assembly of sensors, transmitters, and cleaning devices. When replacing components, there is no need for a complete shutdown, especially for continuous production in chemical, thermal, and other scenarios, reducing downtime losses.

Low maintenance developmentWe are developing sensors with longer lifespans (such as new electrode materials) for upgrading the YST109B-HP880 model, extending calibration and replacement cycles, reducing manual maintenance frequency, and lowering maintenance difficulty in remote areas and high-risk scenarios (such as chemical wastewater).

7、 User reviews

1. Customers of sewage treatment plants

"Previously, manual sampling and detection were carried out every day, but the data lagged behind. When encountering a rainstorm, the pH of influent water dropped sharply, and it was often too late to adjust the dosage. After installing the YST109B-HP880 instrument from Dalian Yister, real-time data fluctuations were observed, and the central control system could automatically link the dosing pump. The effluent compliance rate increased from 95% to 99%, saving a lot of labor and chemical costs. ”

2. Customers of water treatment plants

The pH of raw water is greatly affected by the rainy season, and the dosage was not adjusted in a timely manner before, resulting in excessive turbidity of the effluent. Now using the YST109B-HP880 instrument from Dalian Yister, it can automatically compensate for temperature and the data is very stable. The dosing process follows the pH data, and the quality of the factory water has always been stable without receiving any customer complaints. ”

3. Hospital wastewater treatment clients

The composition of hospital wastewater is complex, with pH fluctuating between high and low, which affects the disinfection effect. After installing the YST109B-HP880 instrument from Dalian Yister in the pre-treatment tank, it can promptly remind us to add acid/alkali. The pH of the disinfected wastewater has always met the standard, and there have been no problems with environmental inspections. You can use it with confidence. ”

4. Smart rural water service customers

The rural sites are scattered. Previously, a dedicated person had to travel to more than ten villages to copy data, which was inefficient. Now, with the installation of the YST109B-HP880 instrument from Dalian Yister and the connection to the cloud platform, the pH values of all sites can be viewed in the office. Any site with abnormal data can be directly notified to local maintenance personnel, saving too much time and manpower. ”

5. Thermal heating customers

When the pH of the circulating water is not well controlled, the pipeline often leaks, and the annual maintenance cost is very high. After installing the YST109B-HP880 instrument from Dalian Yister, the pH was adjusted in real-time to a suitable range. In the past two years, pipeline corrosion has decreased, maintenance costs have decreased by nearly 30%, and there have been no large-scale heating outages during the heating season. ”

8、 Application Cases

1. Case study of a municipal sewage treatment plant

Application scenariosThe processing capacity is 50000 tons/day, and it is necessary to monitor the pH values of three key links: the inlet, aeration tank, and outlet. Our YST109B-HP880 instrument from Dalian Yister is selected.

solve problemsDue to the mixing of industrial wastewater at the inlet, the pH value has repeatedly dropped below 4.0 (due to strong acidity), resulting in the death of microorganisms in the aeration tank and exceeding the effluent standard.

Implementation effectInstall 3 YST109B-HP880 instruments, and automatically add alkali when the pH of the incoming water in the linked dosing system is below 6.0. Maintain the pH of the aeration tank at 7.0-8.0. After one year of operation, the pH compliance rate of the effluent is 100%, the microbial activity in the aeration tank is stable, and the sewage treatment efficiency is improved by 15%.

2. A rural smart water management case

Application scenariosCovering 20 administrative villages in the region, each village has one centralized water supply station, and the pH value of purified water needs to be monitored. The YST109B-HP880 instrument from Dalian Yister is selected.

solve problemsRural water supply stations are mostly located in remote mountainous areas, and the cost of manual inspection is high. There has been a case where the pH of a certain station exceeded the standard and was not detected in a timely manner, resulting in abnormal feeling at the drinking water outlet of villagers.

Implementation effectAll 20 sites are equipped with YST109B-HP880 instruments with IoT capabilities, and data is transmitted in real-time to the district water cloud platform. After six months of operation, a total of three pH abnormalities were warned (all due to seasonal increase in acidity of well water). Maintenance personnel promptly added alkali to adjust the water quality, and there were no further water quality problems. The satisfaction of villagers significantly improved.

3. Case study of wastewater treatment in a chemical industrial park

Application scenariosThe park is responsible for centralized treatment of wastewater from multiple chemical enterprises. It is necessary to monitor the pH values of the regulating tank, neutralization tank, and outlet to ensure that the wastewater meets the discharge standards after treatment. The YST109B-HP880 instrument from Dalian Yister is selected.
solve problems: The pH of wastewater from different enterprises varies greatly. After mixing, the pH of the regulating tank fluctuates violently. It is difficult to accurately control manual dosing, and neutralization leads to subsequent process failures.
Implementation effectOne YST109B-HP880 instrument is installed in each regulating tank and neutralization tank, which automatically controls the amount of acid/alkali added based on pH data. After operation, the pH of the neutralization tank remained stable at 7.0~8.0, and subsequent processes (such as biochemical treatment) were not stopped due to abnormal pH, resulting in a 20% increase in treatment efficiency and a 100% compliance rate for wastewater discharge in the park.
