Power Mechanical Earth Drill
<p>For soil sampling, construction and more, earth augers are gasoline powered and portable. Using one operator, they allow fast and easy drilling. They feature snap-on or screw-on augers and extensions. Engine mounted on wheel-base carrier keeps motor noise ...
Probe Rod, Fiberglass
<p>Ideal for locating buried pipes, tanks and utility lines. Light, non-conductive fiberglass 48" (1219mm) x 0.5" (12.7mm) shaft.</p>
Probe Rod, Steel
<p>Ideal for locating buried pipes, tanks and utility lines. Zinc-plated steel, 36" (914mm) x 0.5" (12.7mm) shaft.</p>
Proctor Penetrometer Set (H-4139)
<p>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 ...
Proving Ring Penetrometer (H-4204)
<p>Used to determine the bearing capacity of subgrades, or to measure soil compaction. Light and easy to handle in the field. A rapid means of determining the penetration resistance of soil in shallow exploration surveys. Includes: 30°, 1 sq. in. (6.45 sq ...
Relative Density of Cohesionless Soils Apparatus
Apparatus determines the relative density of cohesionless, free-draining soils and provides well-defined results on soils that do not respond well to conventional moisture-density impact compaction testing. Soils for which this method is appropriate may contain ...
Resistivity Meter (H-4385)
<p>The resistivity meter can be easily used to measure resistivity of soil in-situ using the 2, 3, or 4 electrode method or with a soil box to measure resistivity of soil or water in the range of distilled to sea water. Resistance measurement range is from ...
Resistivity Test Reel with Soil Pins (H-4388)
<p>Four pin, test reel set for attaining 1-20 ft. depth measurements. Can be used with any 4-terminal meter. Uses 4-electrode Wenner method. Includes 4 separate, color-coded wires of varying lengths from 5 to 65 ft. Jumper leads (2-foot) are supplied for connection ...
Soil Box Leads, set of 4 (H-4387)
<p>Set of 4 wire leads for use with resistivity meters to connect to soil boxes.</p>
Soil Cylinder (H-4385.5)
<p>The Soil Cylinder can be used to satisfy either of the 2-electrode methodsâ€" ASTM G187 or AASHTO T-288 Standards. The body of the Soil Cylinder is made of clear acrylic (allowing easy viewing of sample) with PVC components and the distribution plates (conducting ...
