DFRobot Gravity Analog Electrical Conductivity Sensor – K10 Probe

The DFRobot Gravity Analog Electrical Conductivity Sensor – K10 is designed for measuring high electrical conductivity liquids such as seawater and concentrated brine. It supports a 3.0–5.0V supply and provides a 0–3.2V analog output compatible with Arduino and Raspberry Pi platforms. The AC excitation method reduces electrode polarization, improving measurement stability and extending probe lifespan. Featuring a laboratory-grade K=10 probe and single-point calibration library with automatic buffer recognition, it offers reliable performance for marine aquaculture, aquariums, and high-salinity water quality monitoring applications.

Tips:

This product does not contain a temperature sensor. In order to ensure the measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature and achieve automatic temperature compensation. DS18B20 waterproof temperature sensor can be used.
