Soil moisture conductivity temperature sensors Product Description.

The soil moisture/conductivity/temperature sensor is stable and sensitive and is an important tool for observing and studying the occurrence, evolution and improvement of saline soils as well as water and salt dynamics. By measuring the dielectric constant of the soil, it gives a direct and stable indication of the true moisture content of various soils. The soil moisture sensor measures soil moisture as a percentage by volume and is a soil moisture measurement method that meets current international standards. It is suitable for soil moisture monitoring, scientific experiments, water saving irrigation, greenhouses, flowers and vegetables, grassland pastures, rapid soil testing, plant culture, sewage treatment, fine agriculture, etc.
