คำอธิบาย
เซนเซอร์วัดความชื้นในดิน แบบ Soil Sensor 7 in 1
N P K EC PH T H sensor
For soil temperature and humidity, pH, electrical conductivity (EC) measurements compared with German traditional high-precision sensors and soil drying methods of actual calibration weighing, high precision, fast response, stable output. The salt content in the soil is small, suitable for all soil types. Long-term buried, long-term withstand current, corrosion-resistant, vacuum planting, completely waterproof.
