ES-S225 Series Soil EC PH NPK Temperature Moisture Sensor

ES-S225 series soil sensor is a high-precision and sensitive sensor for online measuring soil humidity / temperature / conductivity(EC) / PH / NPK. This sensor is suitable for measuring soil temperature and moisture.

ES-S225 series soil sensor is a high-precision and sensitive sensor for online measuring soil humidity / temperature / conductivity(EC) / PH / NPK. This sensor is suitable for measuring soil temperature and moisture. After comparison with the original high-precision sensor from Germany and calibration by actual soil drying weighing method, it has high precision, fast response and stable output.

Its electrodes are made of specially treated alloy materials, which can withstand strong external impact and are not easily damaged. IP68 fully sealed design, acid and alkali corrosion resistance, can be buried in the soil or directly put into water for long-term dynamic detection.It is less affected by soil salt content and is suitable for various soil types. It can be buried in the soil for a long time, is resistant to long-term electrolysis, corrosion, vacuum potting, and is completely waterproof.
