Overview
Measuring soil moisture allows a grower to make informed irrigation scheduling decisions that will improve yields and quality while reducing water, fertilizer, labor, and energy costs. LT IRROMETER's are designed to operate in conditions where tensions above 30 cb (kPa) are not expected. Example applications would include avocado orchards on rocky hillsides, citrus in sandy Florida soils, or greenhouses with potting or non-soil growing media. The IRROMETER LT measures soil moisture by interacting with the soil through a porous ceramic tip. As soil dries, it tries to pull water out of the instrument, creating vacuum measured by the gauge. This is a direct, physical measurement of the same tension plant roots experience, requiring no electronics, batteries, or calibrations to operate. IRROMETER tensiometers have been on the market since 1951 and are proven by decades of commercial usage and field research, trusted enough to serve as the calibration standard for other sensors.
IRROMETER tensiometers are constructed of C.A.B., a durable, renewable, plastic designed for outdoor use. Fitted with stainless-steel gauges for many years of reliable service in field conditions, the gauges incorporate a membrane vent which allows them to maintain accuracy during changing conditions without sacrificing protection
