Nuclear Gauge

Moisture/Density Gauge, 8" (200mm) depth in 1" (25mm) increments.— HS-5001EZ081
Humboldt’s HS-5001EZ Moisture/Density Gauge is just that— easy. Easy to operate, easy to power and easy to service. The EZ gauge features a menu-driven control panel with easy-to-use, built-in test routines and auto features, making testing a quick and accurate operation. It also features our innovative trigger release handle that eliminates pinched fingers while providing smooth operation. Available in 8" (200mm) and 12" (300mm) lengths with either 1" (25mm) or 2" (50mm) increments, the EZ gauge provides a single gauge solution to density and moisture measurements. The EZ’s versatility allows it to measure density through direct transmission and backscatter modes, as well as including thin lift and trench modes, as well as moisture determinations. The gauge uses an advanced micro-processor-based technology to provide highly-accurate measurements of density and moisturethat are automatically computed for direct readouts of wet density, dry density, moisture content, percent of moisture, percent of compaction (Proctor or Marshall), void ratio and air voids. The EZ Gauge complies with all pertinent standards: ASTM D6938, D2950, C1040 and AASHTO T310. The gauge is calibrated by the Five-block calibration method.

Heavy-Duty Dynamic Cone Penetrometer— H-4223

The H-4223 Heavy-Duty Dynamic Cone Penetrometer was developed for users requiring a more rugged and longer lasting design, yet portable enough for easy transport to the field. It consists of a 10lb slide hammer assembly with a 24" drop, two 36" extension shafts with 6" increment markings, wrenches and a hardened-steel 60-degree cone tip. All components packed in a heavy-duty carrying case with wheels for easy transport to the job site.

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/cm2. 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.

Field Moisture Oven (FMO)— H-4954

Establishes the moisture-penetration resistance relations of fine-grained soils. Includes these interchangeable needles (area in sq. in. or sq. cm): 1 (6.45), 3/4 (4.84), 1/2 (3.22), 1/3 (2.15), 1/5 (1.29), 1/10 (.65), 1/20 (0.32) 1/30 (0.22cm2) and 1/40 (0.16cm2). Replacement needles available. Meets ASTM D1558. Shipping wt. 17 lbs. (7.7kg).
