MP-508B SOIL HUMIDITY SENSOR

MP-508B sensor can be widely used in soil moisture monitoring, water-saving irrigation, greenhouse control, precision agriculture, road monitoring, hydro meteorology and other fields. It is a soil volume moisture measuring instrument developed by FDR principle. The equipment can be directly used with control instruments, and can also be connected with various data collectors, handheld terminals, etc. For scientific research or irrigation management, mp-508B probe can quickly measure soil moisture by inserting the stainless steel probe into the soil surface or soil profile. 508B water probe can be permanently buried in the ground and connected to a data recorder for long-term measurement. Frequency domain reflectometry (FDR) is a method to measure the soil moisture content by measuring the frequency change caused by the change of the dielectric constant of the sensor in the soil, which is transformed into the voltage or current relationship corresponding to the soil moisture content. It has the characteristics of high accuracy, fast, accurate, continuous fixed-point measurement, no radioactivity and no disturbance to soil.
