Details
In 1951 the Irrometer Co. in Riverside, California began making tensiometers, used initially by soil and plant scientists to measure soil water status in their experiments. Demand for products that helped growers better manage irrigation led to the development of a family of products that measure, sample, and control soil moisture under the trade names Irrometer (tensiometer) and Watermark (electrical resistance granular matrix sensor). For over 60 years Irrometer Co. has dedicated itself to, 'Optimizing Irrigation . . . Maximizing Conservation . . . Worldwide Since 1951.'
