Product Description：
Name：RS485 Moisture / Electric Conductivity / Temperature 3 in 1 Soil Sensor
Type：BND-MEC
MEC10 soil moisture / conductivity / temperature sensor is high sensitivity and stable performance. it is the important tool for observation and study of the occurrence, evolution of saline soil, as well as for improved water and salt dynamic. By measuring the dielectric constant of the soil, can be stably directly reflect the true moisture content of various soils. MEC10 soil moisture sensor measures the soil moisture volume percentage, soil moisture measurement methods in line with current international standards. Suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouse, flowers, vegetables, grass pastures, fast testing of soil, plant culture, sewage treatment, precision agriculture and other occasions.
Sensor has the following characteristics:
(1) soil moisture, Electric conductivity and temperature 3 in 1.
(2) can be used on one of the fertilizer solution , as well as on testing Electric conductivity between the other nutrient and the matrix.
(3) the electrode is used of specially treated alloy material that can withstand strong external shocks, difficult to damage.
(4) it is completely sealed, acid corrosion, can be embedded directly into the soil or water for long-term dynamic testing.
(5) High accuracy, fast response, good interchangeability, measuring probe into the design to ensure accurate and reliable performance.
(6) perfect protection circuit and a variety of signal output interface optional.
