Description
RS485 4-20mA soil temperature moisture moisture conductivity EC PH sensor
CWT-SOIL sensor measures soil temperature and humidity, pH, conductivity (EC), compared with original german high-precision sensors and actual calibration, high-precision weight soil drying method, fast response, stable output. With a small soil salt content, it is suitable for any type of soil. Long-term buried in the ground, long-term electrolysis, corrosion resistance, vacuum pot, completely waterproof.
