Watermark 200SS – Water Stress



Watermark Soil Moisture Sensor


Solid-state electrical resistance sensing device used to measure soil water tension.

SKU: Watermark200S Category:


The sensor consists of a pair of highly corrosion-resistant electrodes embedded in a granular matrix. A current is applied to the WATERMARK to obtain a resistance value. The WATERMARK® meter or monitor correlates resistance to centibars (cb) or kilopascals (kPa) of soil water tension.
The WATERMARK® is designed to be a permanent sensor, placed in the ground to be monitored and “read” as often as necessary with a portable or fixed device. Internally installed gypsum provides some compensation for the effect of salinity levels normally found in agricultural and garden crops.
