SH-TDS200 TDS digital sensor
Overview
The SH-TDS-200 Total Dissolved Solids digital sensor has a built-in NTC temperature sensor and a compensation algorithm that automatically compensates for the effect of temperature on the measured value. The sensor uses RS485 interface and standard Modbus protocol.
Product features
- Electrode constants are stable and unaffected by polarization
- With automatic temperature compensation function
- Internal storage of calibration data
- Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time
- RS485 communication interface, standard Modbus protocol for easy integration.
