Irrometer Soil Moisture Systems
The IRROMETER Tensiometer is the standard in accurate soil moisture measurement, offering growers an inexpensive and reliable means of measuring soil moisture for irrigation scheduling. Because the IRROMETER is a true measurement of soil water potential, the instrument is not affected by salinity and does not require site calibration. The IRROMETER is available in several models, with standard lengths of 6", 12", 18", 24", 36", or 48" dependent on the rooting depth of the specific crop. Longer lengths are available by request.
Because the IRROMETER is manually read from a dial, it is ideal for frequently visited crops such as hoophouse tomatoes or cucumbers. By tracking the change in pressure, you will know when it is time to irrigate your crop, even before you see signs of water stress. For crops under plastic mulches, weed barriers or other soil covers, the IRROMETER allows farmers to better gage when to water and for how long.
IRROMETER
Since 1954 Irrometer has been the industry leader in measuring soil moisture for farms, orchards, vineyards, golf courses and landscaping. Irrometer provides two technologies which measures the water content of a soil the same way your plants will experience soil moisture - through tension or matric pressure.
Other soil moisture meters measure the volume of water in the soil, but volume is not a measure of plant available water which changes with soil texture and water content.

Watermark Sensor
The 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. The sensor consists of a pair of highly corrosion resistant electrodes that are imbedded within a granular matrix which absorbs water in balence with the surrounding soils.
The Watermark Sensor functions much like the Irrometer, but provides an digital output which can be read with a hand held meter, or transmitted to a gateway, such as the Temp@lert Gateways for uploading to a cloud based dashboard.
Compared to the Irrometer, the Watermark sensors requires less maintenance, and can be left in the field for several years.
