Irrometer Model LT, 36”

The Model LT (Low Tension) is designed for use in coarse sandy soils and non-soil media such as peat, bark, sand, perlite, and vermiculite. This Irrometer is an excellent choice for operation in any soil when the moisture is being managed close to field capacity. The Model LT features a tough Butyrate plastic body that is impervious to soil chemicals, a replaceable “quick-flo” ceramic tip that provides fast response to variations in soil moisture, and a hermetically sealed gauge with a range of 0 to 40 centibars or kilopascals in increments of 1 cb (kPa). In addition, the gauge features a membrane vent for better temperature-related and elevation-related compensation, a 2.5˝ diameter face, and a rustproof stainless steel body. The instrument’s ceramic tip has an O-ring seal and is threaded for simple replacement in the field. A large reservoir with a screw cap holds a reserve supply of water to replace water lost by the action of drying soil. Partially unscrewing the cap releases air and fills the tube from the reservoir. All ceramic-to-plastic connections are guaranteed leakproof. Irrometer fluid, supplied with the Service Unit accessory, adds color to the water for easy water level observation. The Model LT Irrometer requires the Service Unit accessory and the Soil Coring Tool with the initial order.
