IRROMETER Watermark Soil Moisture Sensor with 10-ft. Cable

Item No: R38101


IRROMETER Watermark Soil Moisture Sensor with 10-ft. Cable

Plant these specially designed 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 and gives accurate readings even with salinity levels found in agricultural crops and landscapes. Sensors are inexpensive and can be placed anywhere in your soil profile to monitor moisture levels at different depths and locations. Each sensor includes 10-ft. of cable (extendible to 1,000-ft. with 18 ga. wire). Hand-held Digital Meter (Item No. R38201) simply clips onto the Watermark sensor and displays soil water tension readings. The unit of measure used is centibars (cb) or kilopascals (kPa) of tension. The higher the reading is, the drier your soil [example: 0 cb (kPa) is saturated where 200 cb (kPa) is dry]. One Digital Meter will read all of your Watermark sensors. USA made.

NOTE: The Watermark Digital Meter is required to read sensors (sold separately under item No. R38201).
