SM300 soil moisture temperature sensor

The SM300 soil moisture temperature sensor is a research-grade soil moisture temperature sensor whose volumetric water content measurement results can reach 2.5%. SM300 can not only meet the requirements of various controllers and data acquisition systems on the market. The low price allows the SM300 soil moisture temperature sensor to be more widely used in agricultural production. The design is sturdy and not only can be used as a portable instrument, but also can be installed for a long time. When used as a portable instrument, it can also penetrate deep into the soil borehole, and measure the soil moisture temperature and moisture content of the profile in time and conveniently.
