Conductivity & DO Sensors
Digital Conductivity Sensor YG-AP/30
The digital conductivity / TDS sensor is a digital sensor developed by YuanGan for online drinking-water quality monitoring, with the digital circuit integrated inside the sensor. It monitors conductivity / TDS and temperature in real time, using an RS-485 interface and the Modbus-RTU communication protocol.
Typical applications
- Domestic Drinking Water
- Surface Water
- Groundwater
- Online conductivity monitoring of wastewater and more
