Pocket Penetrometer

Pocket Penetrometer

Standards:

ASTM D2573-94

Description:

• Designed for the rapid determination of soil consistency, shear strength and approximate Unconfined Compression Strength. Soil Testing Equipment
• Penetrometer is constructed from anodized aluminum and measures 6-1/4”Lx 7/8” dia.
• Pocket Penetrometer Soil Testing Equipment

Operation:

• The ring on the barrel of the Penetrometer holds the maximum reading of the scale for easy reading.
• Slide the ring down against the instrument hande.Soil Testing Equipment
• Grip the knurled portion of the Penetrometer into the soil to the groove located 1/4’’ from the tip.
• Read the unconfined compression strength directly in tons per square foot (TSF) or kilograms per square centimeter (kg/cm2) from the scale. The reading is located on the lower side of the ring – side closest to knurled hande.

Features:

• The easy-to-read scale indicates strength from 0 to 4.5 tons per sq ft.
• The new pocket penetrometer, weighing less than 5 ounces, reduces the human error in classification of cohesive soils.
• The penetrometer can also be used with the torsional vane shear tester for rapid estimation of the degree of internal friction of soil. Soil Testing Equipment

Specification:

Notes:

• Select test spots with a smooth surface.
• Hold the Pocket Penetrometer at right angles to the surface being tested.
• To minimize errors, take several readings near each other, discard those readings which may vary significantly from the majority and average the readings.
• When the Adapter Foot is used for very soft soils, divide the reading by 16 to botain the correct compression strength of the soil. Push the foot into the soil the total thinkness of the Adapter Foot.
