Brand：Erun
Dual-channel touch online water quality monitor
Model：ERUN-SZ2-B
DO, pH, ORP, conductivity (salinity/TDS), turbidity SS, etc.
Dual-channel intelligent online multi-parameter water quality tester is a high-precision, multi-functional, intelligent in one of the water quality monitoring equipment, designed for environmental protection, water, agriculture, food, scientific research and other fields. The instrument is capable of real-time, continuous monitoring of a variety of key parameters in the water body, including but not limited to DO, pH, ORP, conductivity (salinity/TDS), turbidity SS, chlorophyll, blue-green algae, oil in the water, COD, ammonia nitrogen, transparency, CDOM, chromaticity, etc., to provide accurate and reliable data support for water quality safety monitoring, pollution early warning, environmental governance.

Adopting advanced fluorescence sensing technology, it is easier than traditional manual counting; |
It can be used without electrolyte, rapid testing, avoiding the impact of shelving water samples; |
With self-cleaning brushes to prevent bio-adhesion and longer maintenance intervals; |
Built-in calibration parameters for easy field use and secondary calibration; |
Using RS485 digital output, standard Modbus protocol; |
