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. 

An IRROMETER will measure the actual soil water tension, which indicates the effort required by root systems to extract water from the soil.

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 operates on the tensiometer principle. Consisting of a sealed water filled tube equipped with a special vacuum gauge and with a porous tip that is installed in the ground at desired root zone depths. In dry soil, water is drawn out of the instrument, reducing the water volume in the instrument, and creating a partial vacuum which is registered on the gauge, the drier the soil, the higher the reading.

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.
