The Acclima Digital TDT® Soil Moisture Sensor represents a revolutionary advance in the irrigation industry. It is the first moisture sensor to incorporate the accuracy of digitized Time Domain Transmissometry in a low-cost instrument, providing highly accurate absolute readings of soil moisture under all conditions of temperature and soil chemistry under which crops will grow. No other sensor on the market matches its accuracy and stability. Independent test data from the Center for Irrigation Technology and other leading soil physicists verifies this extraordinary claim and are available upon request.
