Water Quality Analyzers And Sensors

Online Water Quality Analyzer for Water Plants

The highly versatile universal transmitter connects freely with both digital and analog sensors, measuring parameters including pH, DO, ORP, conductance, turbidity, SS, chlorophyll, blue-green algae, residual chlorine, UVCOD, ionic ammonia nitrogen, nitrate, and transparency. Users can opt for single-channel (one sensor) or two-channel (two sensors) configurations to cut costs and save installation space. All digital sensor interfaces work directly, while analog sensors use type-specific modules—enabling plug-and-play, with quick electrode installation and replacement. Beyond displaying sensor data, it allows users to configure 4-20 mA analog output and calibrate via interface prompts, plus support relay control and digital communication. Widely used in sewage/water plants, monitoring stations, surface water systems, aquaculture, and industry, it meets diverse monitoring needs.
