Soil temperature sensor (transmitter) uses high-precision thermistor as the induction component, which has the characteristics of high measurement accuracy and good stability. The signal transmitter uses an advanced circuit integrated module, which can convert the temperature into the corresponding voltage or current signal according to the different needs of the user. The instrument volume is small, convenient and portable, reliable performance; using proprietary line, good linear, strong load capacity, long transmission distance, strong anti-interference ability. Can be widely used in meteorology, environment, laboratory, industry and agriculture and other fields of temperature measurement.
