Soil— Field 22 Shear Strength H-4205 Dial Pocket Penetrometer Kit— H-4205 A sophisticated pocket penetrometer offering greater capacity and sensitivity than others. Maximum value is retained on the dial until released via push-button. Inner dial scale 0 to 6.0, with 0.1 divisions in tsf and kg/cm 2 . Outer scale gives load strength over 0 to 11.0 with 0.1 divisions in tsf and kg. This reading is used with charts (included) to estimate safe bearing pressures, depending on plunger used and soil type. Values indicated relate to the standard 1/4" dia. plunger. In addition, readings with four other included plungers (10, 15, 20, 25mm) indicate safe bearing pressures for foundations in consolidated soils over a range of sandy to clay-type soils. The 2.5" (63mm) dia. dial can be easily recalibrated using register plates (included) and any readable scale of 10-15 lbs. capacity. Includes data tables, register plates, instructions, and carrying case. H-4221.3A H-4227 H-4227.2 H-4221 H-4221.1 H-4221.4 1.800.544.7220 • www.humboldtmfg.com H-4200F H-4200 Soil Penetrometer, Pocket Type— H-4200 For use by field personnel to check visual classification of soils. Verifies whether excavation side walls require shoring, based on OSHA cohesive soils classifications. Indicates consistency, shear strength, and approximate unconfined shear strength. Direct- reading scale—in tons/sq ft, or kg/sq cm—corresponds to equivalent unconfined compressive strength. Range: 0 to 4.5 tons. High quality construction. Includes belt-loop style carrying case and operating instructions. Should not replace laboratory testing or field analysis, or be used to produce foundation design data. Penetrometer Adapter Foot— H-4200F Adapter foot is recommended when testing extremely low strength cohesive soils. 1" (25mm) dia. foot, compared to the 1/4" (6.35mm) penetrometer piston, increases the effective area measured by 16 times. Divide by 16 to obtain correct unconfined compressive strength when the reading in tons per square foot or kilograms per square centimeter is on the low-load side. Geovane Soil Shear Strength Tester— H-4221 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 Blade (33mm)— H-4221.1 Extension Rod 12" (300mm)— H-4221.2A Extension Rod 19.7" (500mm)— H-4221.3A Extension Rod Adapter— H-4221.4 Vane Inspection Set— H-4227 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 sizes 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 for effects of soil friction. All items come in a compartmentalized vinyl carrying case with three wrenches. Shipping Weight: 6 lb (3kg). Extension rod, 0.5 meter— H-4227.1 50.8 x 101.6mm Vane— H-4227.2 Measuring range is 0 to 8.125kPa (0.08 TSF)
www.humboldtmfg.com • 1.800.544.7220 Torvane Shear Tester Set, Metal— H-4212M This device is recommended for the rapid determination of shear strength of cohesive soils, in either the field or laboratory. The tester may be used for in-place testing of pits or trenches It permits the determination of a large number of strength values with different orientation of failure planes. It is simple to use with sample trimming eliminated. All that is needed is a reasonably flat surface 25mm in diameter. It gives repeatable values in homogeneous clay. Extensive laboratory testing indicates excellent agreement between the unconfined compression test and the shear tester. The simultaneous use of the TST and a pocket penetrometer allows rapid evaluation of the degree of the internal friction of soil in shear strength or to determine if the soil is essentially cohesive. Torvane Shear Tester Set, Plastic— H-4212 Similar to H-4212M, but made of plastic. Comes in plastic case. Soil Color Charts— H-4368 Soil color is measured by comparing with color chart. Set includes nine hue charts displaying 322 colors on a neutral gray chart stock. Apertures are cut between the adjacent color chips so sample may be evaluated directly against the standard colors. Charts, diagrams and interleaves fit into a six-ring looseleaf binder. Charts are 7-1/4 x 4-1/4" (184x108mm), small enough for field use Tropical Soil Charts— H-4368T Tropical Soil Charts for use with H-4368. Special charts for reddish tropical soils. Recommended for regions such as South and Central America, Africa, India, Malaysia, and similar tropical areas. Includes two charts that fit into H-4368 binder. Sand Grading Chart— H-4369 Unique chart useful to engineers, geologists, contractors, and soil scientists for uniform classification of sands. Soil Strength Classifier, 125lbf / 55kgf Capacity— H-4180.125 Soil Strength Classifier, 250lbf / 110kgf Capacity— H-4180.250 Soil Strength Classifier, 350lbf / 160kgf Capacity— H-4180.350 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) Soil Strength Classifier, 125lbf / 55kgf Capacity— H-4186.125 Soil Strength Classifier, 250lbf / 110kgf Capacity— H-4186.250 Soil Strength Classifier, 350lbf / 160kgf Capacity— H-4186.350 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.
