Product Description

Product Description

SEM225 series soil sensor is a high-precision and sensitive sensor for online measuring soil humidity / temperature / conductivity(EC) / PH / NPK. Compared with the original high-precision sensor of Germany and calibrated by the actual drying and weighing method of soil, it has high precision, fast response and stable output. Agricultural sensor series products are widely used in agricultural greenhouses, fower cultivation, pasture grassland and other occasions.
