Imported portable dissolved oxygen meters are widely used in the fields of sewers, food industry, and aquaculture/aquariums due to their high precision, fast response, and reliable performance. The following are specific application scenarios and advantages analysis:

1、 Sewer and sewage treatment: real-time monitoring, optimizing treatment efficiency

1. Application scenarios

Monitoring of inflow and outflow of sewage treatment plants: Evaluating the activity of microorganisms in biological treatment tanks by measuring dissolved oxygen (DO) content. For example, domestic sewage treatment needs to maintain DO at 2-4mg/L to ensure the efficiency of organic matter decomposition and avoid excessive discharge.

Aeration equipment control: dynamically adjust the aeration rate based on DO data to ensure microbial oxygen demand and reduce energy consumption. For example, in high-density aquaculture wastewater treatment, precise control of DO can reduce electricity costs by more than 30%.

Pollution tracing: If the DO at a certain point is abnormally low, it may indicate that industrial wastewater is being discharged illegally or domestic sewage is being discharged directly, and further investigation of the pollution source is needed.

2. Technical advantages

Fluorescence sensor: No electrolyte required, resistant to hydrogen sulfide interference, response time as short as 2 seconds, suitable for complex water quality monitoring.

Waterproof design: IP67 protection level, suitable for humid and corrosive environments, ensuring long-term stable operation.

Data storage and transmission: Supports USB or Bluetooth connection, can be integrated into water quality monitoring systems, and achieve remote data management.

2、 Imported portable dissolved oxygen meter for food industry: ensuring quality and extending shelf life

1. Application scenarios

Production water testing: In beverage production, if the dissolved oxygen (DO) in the water is too high, it may lead to the oxidation and decomposition of vitamins, affecting their nutritional value and taste. The portable dissolved oxygen meter can adjust the deoxygenation process in real time to ensure that the water quality meets the standard.

Packaging process optimization: In the production of bottled water and PET bottled beverages, controlling the oxygen content in the filling process can extend the shelf life. For example, the RO-103 series can detect the oxygen concentration inside sealed packaging, helping companies optimize the filling gas replacement ratio.

Drug production: Injections require high DO control in water, and portable dissolved oxygen meters can accurately detect and prevent component oxidation, ensuring drug stability and efficacy.

2. Technical advantages

Trace oxygen detection: Some models have a measurement range of 0.00-25.0%, meeting the strict requirements of the food and pharmaceutical industries for trace oxygen.

Corrosion resistance: Designed for organic solvent environments, sensor materials are resistant to chemical corrosion to ensure long-term accuracy.

Quick Calibration: Supports single point or two-point calibration, easy to operate, and reduces downtime.

3、 Imported portable dissolved oxygen meter for aquaculture/aquariums: precise oxygen control to improve survival rate

1. Application scenarios

Aquaculture: In freshwater and marine aquaculture, dissolved oxygen (DO) is the "lifeline" for the growth of fish and shrimp. For example, high-density aquaculture ponds require real-time monitoring of dissolved oxygen (DO) to avoid the phenomenon of "floating head" or "flooding". The portable dissolved oxygen meter can be linked to the oxygenation equipment and automatically adjust the operating time and power.

Aquarium maintenance: Large aquariums need to maintain a dissolved oxygen (DO) level of 5-8mg/L to ensure the health of corals and fish. Portable devices can quickly detect DO distribution in different areas and optimize water flow and aeration design.

Research experiment: When studying the relationship between dissolved oxygen (DO) and the behavior and metabolism of aquatic organisms, portable dissolved oxygen meters can provide high-precision data support.

2. Technical advantages

Multi parameter measurement: Some models can simultaneously display DO concentration, saturation, temperature, and salinity compensation values, adapting to different water quality conditions.

Long endurance: Powered by alkaline or rechargeable batteries, it can work continuously for up to 1000 hours, meeting the needs of long-term monitoring in the wild.

User friendly design: Large LCD backlit display screen, easy to operate, even non professionals can quickly get started.
