75 Years of Trust
From a small Riverside workshop to a global leader in soil water measurement technology, our story is built on precision, reliability, and a commitment to helping growers succeed.
A Legacy of Innovation
The Beginning
Arlington, CA citrus grower and inventor T.W. Prosser became familliar with research tensiometers being used at University of California, Riverside. He set to work on producting a commercially viable version, and brought it to market in 1951.
WATERMARK Innovation
Glen Larson developed the early versions of the patented WATERMARK granular matrix sensor technology, a new approach to soil moisture measurement that would become an industry standard.
Product Refinement
IRROMETER tensiometers are updated with enhanced reservoirs, replaceable tips, and and optional low tension version. The modern stainless steel cased version of the WATERMARK Sensor (200SS) is developed, begining widespread adoption.
Data Solutions
IRROMETER begins manufacuturing their own line of data loggers (900M, 950R/T) and associated accessories for advanced data collection.
Remote Data Collection
Cellular technology is added as an option to existing data devices, along with the introduction of the IRROmesh wireless mesh sensor network.
