Renke 4-20MA output waterproof irrigation soil moisture sensor

Our sensor for soil temperature and moisture 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. ADVANTAGES: 1: High precision measurement, rapid response, good exchange ability 2: Good tightness, corrosion resistance, can be used in the soil for a long time. 3: Flame retardant epoxy resin curing, completely waterproof, can withstand strong external impact. 4: Steel needles are made of high quality materials that can with stand long-term electrolysis , acid and alkali corrosion in soil. 5: Steel needles are made of high quality materials that can withstand long-term.
