Product Details
Laboratory desktop multi parameter sewage quality analysis and determination instrumentIt is a key equipment for sewage treatment process control and discharge supervision, which can quickly and accurately measure dozens of core indicators such as COD, BOD ₅, ammonia nitrogen, total phosphorus, total nitrogen, pH value, suspended solids, chromaticity, and fecal coliform bacteria in water, providing scientific basis for the daily operation, process optimization, and discharge compliance of sewage treatment plants.
According to the 2024 report from the ecological environment unit, about 17% of sewage treatment plants in China have been punished for exceeding the effluent quality standards, with COD, ammonia nitrogen, and total phosphorus accounting for over 65% of the total. The traditional single parameter detection method is time-consuming, consumes large amounts of reagents, and has high human error. The ERUN-ST series sewage treatment plant laboratory desktop multi parameter water quality analysis and determination instrument integrates spectrophotometry, electrochemical method, and mercury free pressure difference BOD determination technology. A single test can complete more than 8 core parameters within 30 minutes, with measurement error controlled within ± 1.0%, significantly improving laboratory efficiency and data reliability.
Desktop multi parameter water quality analysis and testing instrument for sewage plant laboratory. Product features:
★Simultaneous measurement of multiple parameters
Multiple indicators such as pH, conductivity, dissolved oxygen, turbidity, temperature, and ion concentration can be measured at once without the need to use multiple devices separately. Modern multi parameter water quality analyzers often support simultaneous monitoring of 6-12 or even more parameters.
★High accuracy and stability
Compared to simple on-site instruments, desktop instruments are more suitable for laboratory environments, with stable measurement and good repeatability. They are suitable for scenarios with strict requirements such as sewage effluent quality testing, discharge compliance, and environmental monitoring.
★Convenient data storage and management
Many instruments support data storage, export, and analysis, facilitating the generation of reports, tracking of water quality trends, long-term recording, and data management.
★Wide applicability, compatible with multiple water quality types
Whether it's urban sewage, industrial wastewater, surface water, groundwater, or recycled water, this instrument can be used for comprehensive testing; Suitable for sewage plant laboratories, environmental testing institutions, scientific research laboratories, water quality monitoring stations, etc.
