Measuring and Logging Soil Moisture Temperature Humidity EC PH NPK Sensor with HMI touch screen
Important Reminder The measurement of NPK adopts the general rapid detection method, so there are certain error, Use with caution for planting reference.The existing electronic measuring method cannot accurately measure NPK, the error is big, sensor only show trend of NPK. Measuring and Logging Soil Moisture Temperature Humidity EC PH NPK Sensor with HMI touch screen CWT-SOIL sensor is for soil temperature and moisture, PH, conductivity (EC),measurement, compared with the original German high-precision sensors and soil drying method of weighing the actual calibration, high precision, fast response, stable output. By the soil salt content of small, suitable for all kinds of soil. Long-term buried in the soil, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
