WATERMARK Soil Moisture Sensors
In use since 1978, the patented WATERMARK sensor is an electrical sensing device that is buried in the active root zone to measure soil water tension.
The sensor consists of corrosion resistant electrodes embedded within a specialized granular matrix. Water in the soil exchanges with the sensor matrix, providing a measurement of centibars (or kPa) of soil water tension equivalent to the readings from an SR or LT tensiometer.
The WATERMARK is designed to be a permanent sensor, left in the soil to be read by logging devices or handheld readers. We offer our own reading solutions, but the sensor is also widely used by industry partners in their own applications.
