LS-EC100 Wireless Irrigation Controller Soil Conductivity Sensor For Moisture / Temperature
LS-EC100 soil conductivity sensor has stable performance and high sensitivity. It is used to monitor and study the soil’s salinity. As an important tool for soil moisture monitoring, LS-EC100 is widely used for scientific experiment, water-saving irrigation, greenhouse, flower and vegetable irrigation, plant irrigation, soil measurement, waste water treatment, agriculture monitoring and so on.
LS-EC100 sensor has the following characteristics:
(1) Can measure conductivity of soil, fertilizer solution, and other nutrients.
(2) With special alloy materials, electrode can bear strong external impact to prevent damage.
(3) Good sealness, non-corrosiveness of acid and alkali. Can be buried in the soil or directly thrown into the water for long-term dynamic detection.
(4) high precision, fast response, good interchangeability, probe plug-in design to ensure accurate measurement, reliable performance.
(5) perfect protection circuit. Kinds of signal output interface optional.
