The Irrometer, Company has been in business since 1951, manufacturing soil moisture measuring, controlling, and sampling instruments used worldwide for scheduling irrigation.  Principal brand names are Irrometer (Tensiometer) and Watermark (electrical resistance granular matrix sensor).  These soil water potential/tension measuring instruments originated in the early part of the 20th Century, and were used by soil and plant scientists to measure soil water status in their experiments.

The Irrometer company was the first to produce commercially viable versions of this technology, and although this technology is scientific instrumentation, the instruments are inexpensive and easy to use for all irrgation applications.  The use of soil moisture based irrigation scheduling has been proven an efficient way to deliver irrigation water for agriculture, nursery/greenhouse and landscape/urban irrigation.  Further, the instrumentation can be used for controlling (automatic irrigation systems) and signaling (for data logging systems and inputs to weather stations).
