Portable, Static Cone Penetrometer Information The H-4210A Static Cone Penetrometer is an unparalleled device for measuring soil consistency. It is specifically designed for use in fine grained, soft soils to depths as much as 30 feet. The basic unit is totally self contained, weighs 5 Ib, and is set up for a 2-ft maximum depth. It is intended to be operated by one person and requires no auxiliary equipment. The device is extremely rugged and is built for day-in, day-out use.
How To Use the Cone Index The reading (Qc) is in kg/cm2 which is essentially equal to ton/ft2. The cone index (Qc) is read directly. The correlation between the cone index and soil constants is not absolute. Generally, the following results have been determined through extensive field use of the unit. Further verification of correlation in your local soil types is essential. Humboldt Mfg. accepts no liability for the accuracy of the suggested correlations.
Maintenance Your Cone Penetrometer is a ruggedly-designed device intended to tolerate a reasonable amount of field abuse. The most critical requirement is keeping foreign matter outside the annulus between the Inner and Outer Rods. It is recommended that a drop or two of lightweight machine oil be applied frequently to the annulus. (A schedule of every 2-3 days is recommended if the unit is being used daily). The Inner Rod is a surface-ground stainless steel rod which will not rust.
