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.
