Geovane Soil Shear Strength Tester

The Geovane is a hand-held instrument used for determining soil shear strength providing the reading in kPa. The device is simple to use. A 19mm vane blade is screwed into the base of the Geovane and the vane is pushed into the soil. Simply rotate the Geovane at a rate of 1 revolution per minute and take a reading off the face when the soil fails. The pointer stays in place when failure occurs allowing you to look up the indicated reading on the supplied calibration chart to get your reading in kPa from zero to 200. Through the use of the optional 33mm vane, readings can be measured between the range of zero to 40 kPa. Extension rods are available to increase the depth measurement capabilities of the unit. The H-4221.4 Adapter is needed to attach extension rods to the Geovane. The Geovane is supplied complete with a 19mm vane blade, wrenches and a carrying case.

Vane Inspection Set

The Vane Inspection Set provides a rapid check of the stability of foundations, excavations and trenches in clay. The total range is 0 to 260kPa (0 to 2.6 ton/sq. ft.). The scale built into the handle holds the peak value until reset. Accuracy is ±10%. Three different size vanes are included with the set (16 x 32, 20 x 40 and 25.4 x 50.8mm). The effective ranges are 0 to 260, 0 to 130 and 0 to 65kPa (0 to 2.6, 0 to 1.3 and 0 to 0.65 tsf). A “dummy” vane is also included to calibrate the six 0.5 meter long extension rods included for effects of soil friction. All items come in a compartmentalized hard carrying case with two wrenches. Shipping Weight: 11 lb (5kg).
