KACISE KWS101 Digital Turbidity - compensating COD Sensor
1.Instruction
KACISE KWS101 Digital Turbidity - compensating COD Sensor stands out for its unique turbidity compensation feature. It accurately measures COD in the range of 0 - 1500mg/L with a resolution of 0.01mg/L. By integrating a turbidity detection light source, it automatically adjusts for turbidity interference in the water being tested. This digital sensor has RS - 485 output and follows Modbus protocol. Its compact size and easy installation make it suitable for various online water quality monitoring scenarios.
2.Features
Digital sensor, digital RS-485 output, Modbus protocol;
Can measure parameters such as COD, TOC, turbidity and temperature;
Automatically compensate for turbidity interference and have excellent test performance;
With self-cleaning brush to prevent biological attachment and longer maintenance cycle;
Built-in calibration parameters for easy on-site use and secondary calibration.
