Soil Strength Classifier

Hand-lever operated, soil strength classifier provides fast manual approximations of unconfined compressive strength on many soil types in the field or lab. Platen accepts up to 2" (51mm) sample diameters and up to 4-1/2" (114mm) lengths. Reads loads on 4-1/4" (108mm) dial face with ±1% of dial capacity as held with second maximum-reading pointer. Dial has 1 lbf divisions on outer scale, 1 kgf divisions on inner scale. Unit has cast aluminum housing. Base dimensions are: 5-3/4 x 10-1/4" (146 x 260mm), drilled for optional bench mounting. Calibration spring confirms proper operation; order separately. Shipping wt. 18 lbs. (8.2kg)

The H-4186 Series Soil Classifiers are identical to the H-4180 Series except they feature a geared hand-wheel loading system. This unique system provides a more uniform rate of load and easier loading and recording of peak values by a single operator.
