Soil Temperature, Moisture & EC Sensor (SMKB-SMTEC)
The new developed soil moisture temperature EC three-in -one sensor is a soil sensor developed with a new technical scheme, which can measure soil moisture, temperature and conductivity at the same time, and carry out compensation calculation among parameters, eliminating the influence of conduc- -tivity on water , temperature on water and temperature on conductivity , can perform compensation operation and accurate evaluation . This product can be used to measure the moisture content of saline-alkali land, w hich is not affected by the salt content of soil and can accurately measure the moisture content of soil. It adopts imported epoxy resin, high quality stainless steel, and more resi stance to acid and alkali corrosion, steel needle isolation, never electrolysis, wi th more than 3 years of service life.
With the multi-directional function of power line, ground line and signal line, can prevent the damage caused by reverse connection, wrong connection and so on.
