Standard Tensiometer, 60 inches (152 cm) length, 1 bar gauge. The 2710ARL Tensiometer is a simple, versatile, and inexpensive instrument which provides a direct measurement of soil water tension. The modular design allows easy replacement of the ceramic cup and dial gauge, and addition of extension tubes and the Service Cap. Series 0240 Insertion Tools can be used for coring a hole in the soil to accept these units. The 2710K1 Service Kit, available separately, is used to refill and maintain the tensiometer. Unique modular construction allows for easy replacement of the porous ceramic cup and re-calibrator style dial gauge for zero setting and re-calibration.
