Irrometer, P-2001, Model "P" Portable Soil Water Tension Detector with 12" Extension Tip P (Portable) was developed to assist the user in determining soil moisture status in temporary monitoring situations. The Instrument measures in centibars (cb) or kilopascals (kPa) of soil water tension. This value represents the energy a plant s root system uses to draw water from the soil. Understanding soil moisture activity helps the user make informed irrigation scheduling decisions. Unlike other model IRROMETERs which are intended for permanent installation, the Model P is designed to be installed in a temporary situation so that the user can make a spot check of soil water tension and then relocate the instrument to other locations. Each site reading may take from minutes to hours, depending on soil conditions. Includes: Reservoir Air-free gauge chamber Hermetically sealed Irrometer vacuum gauge with dual scale of centibars (cb) and kilopascals (kPa) [ 0-100 cb (kPa) range] Insertion handle 12 in. (30 cm) extension tip Features: 0-100 cb (kPa) range gauge Air free gauge gives accurate readings Large reservoir makes maintenance easy Hermetically sealed gauge designed for harsh environments Chrome plated handle makes frequent installation and removal easy Operating Principle The IRROMETER operates on the tensiometer principle, which measures soil water tension. Soil water tension is the energy (vacuum) applied to soil by the plant as it draws in water for nutrition. This force is measuin centibars (cb) or kilopascals (kPa) of tension with a high reading indicating the dry end of the scale and a low reading indicating the wet end of the scale. The IRROMETER instrument consists of a sealed, fluid filled tube that is equipped with a porous ceramic tip and a special vacuum gauge. They are installed in the ground with the tips placed at desiroot zone depths. As the soil dries (increasing tension), fluid is drawn out of the instrument.
