In use since 1978, the patented WATERMARK sensor is a solid-state electrical resistance sensing device that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the WATERMARK Sensor. The sensor cons...

The WATERMARK Meter is a hand held device designed for reading WATERMARK sensors in the field. The digital readout displays the sensors’ soil moisture status in centibars (cb) or kilopascals (kPa) of soil water tension. This value represents the energy a plant’s root system uses to draw water fr...

WATERMARK Electronic Module — WEM OPERATING PRINCIPLE: The WATERMARK Electronic Module works in conjunction with a residential or commercial type irrigation controller to suspend irrigation when soil moisture status is appropriate for good plant heath. The included WATERMARK soil moisture sensor...

Designed for home owners and using the proven WATERMARK sensor, this simple device “controls the controller” so that watering is only allowed when necessary based on soil moisture status. One sensor and an adjustment range designed specifically for turf grass make this an affordable and simple w...

The Multiple Hydrozone System, both wired (MHS) and wireless (W-MHS), works with your existing AC irrigation controller to eliminate programmed irrigations when plants have adequate soil moisture. It makes decisions to open or close the valve common wire or signals the controller, based on sever...
