“Jet-Fill” Tensiometer Model 2725 ARL, 12”

Vacuum gauge with large 2” easy-reading dial face is graduated from 0 to 100 centibars of soil suction. Hermetically-sealed, resilient, neoprene jacket protects against weather and shock. Neoprene O-ring stem seal permits dial gauge to be removed or oriented in convenient reading position with perfect vacuum seal assured, and thus provides desirable flexibility for transportation and use of instrument. A push of the button instantly removes accumulated air and fills unit with water. Replaceable screw-on porous ceramic tip has ten times the transmission rate of other ceramic tips, yet limits air collection to less than 1/3 of other tips. Angle molded port in sidewall provides rigid, strong connection and keeps vacuum gauge filled with water. Large reservoir holds sufficient water for months of servicing. Clear plastic, 7/8” O.D., rigid, heavy-wall body tube essential for accurate readings at high soil suction values is immune to weather effects and soil chemical action. The vent screw located on the side of the gauge is used to equalize the pressure at your elevation. Size of unit is distance from installation line to center of tip. Installation line molded into body tubing. Complete instructions included. How Tensiometers and Irrometers Work. Tensiometers and Irrometers continuously measure and display soil moisture at the root zone of the plant. Using this information, you know when to irrigate and when not to. You can prevent over-irrigation, waste of water and fertilizer. You can also increase the yield and quality of crops by eliminating soil sampling, calibrations and guesswork from your irrigation program. These instruments consist of a sealed water-filled tube, equipped with a porous tip at the bottom. The tube is installed in the ground at desired root zone depths. In dry soil, water is drawn out of the instrument. The reduced water volume in the instrument creates a partial vacuum which is registered on the gauge. This vacuum draws water back into the tube as irrigation and rainfall reverse this action. Readings are in centibars of soil suction – showing you exactly how hard the roots need to work to extract needed moisture from the soil.
