Watermark Soil Moisture Sensor

Plant these specially designed gypsum block soil moisture sensors in the root zone of your plants without detracting from the visual appearance of your landscape. They require no water or vacuum gauge, which makes them maintenance free. This Watermark sensor will not dissolve in the soil like other gypsum block sensors and still gives accurate readings even with salinity levels found in agricultural crops and landscapes. Hand-held Digital Meter (Item No. R38201) simply clips onto the sensor and reads 0 (saturated) to 200 (dry) centibars. Sensors are inexpensive and can be placed anywhere in your soil profile to monitor moisture levels at different depths and locations. One Digital Meter will read all of your Watermark sensors. Each sensor includes 10-ft. of cable (extendible to 1,000-ft. with 2-wire cable). USA made.
