(includes pelican case)
Dual-Mass Dynamic Cone Penetrometer— H-4218B
The Standard DCP Kit measures the shear strength of soil with
a CBR between 0.5-100% and psf from 455-7072. This singleoperator
kit is ideal for state/county/city highway departments
and geotech firms. CBR and psf can be estimated in the field
from tables in the manual and plotted using Corps of
Engineers Excel template included on CD. It comes with a
stainless steel dual-mass (17.6/10.1 lb) hammer and quick-
connect upper rod, 30 inch drive rod (27 ¼ inch penetration),
a 40 inch vertical scale, upper and lower scale mounts, a roll
of marking tape with pen, a reusable hardened point and a
disposable cone adapter with 25 disposable cones for fast
and easy extraction of the instrument from hard/cohesive soil.
The kit also includes a crush-proof Pelican carrying case with
transport wheels and wrench set. Shipping: 45" x 16" x 7",
54 Lbs.
Additional disposable cones, adapters, and hardened
points are available.

Economy, Single-Mass DCP— H-4218E
This Economy DCP Kit is used to estimate the shear strength of
soil with a CBR between 10-100 and psf from 762-7072. Tables in
the manual provide correlations to CBR and psf values for the
penetration rates at 2 inch, 4 inch and 6 inch intervals. Affordably
priced, this single-operator kit comes with a 37-3/4 inch drive rod
that is marked in 2 inch increments, and a reusable hardened point.
The single mass (17.6 lb) structural steel hammer is standard with
this kit. Also included are a manual, two Quick Connect pins, two
wrenches and 3-in-1 oil.
Please Note: The Economy DCP Kit DOES NOT come with a
carrying case.
Magnetic Ruler for the DCP— H-4218.MR
Reduces time for one person to conduct DCP test.
The Magnetic Ruler is a battery-operated (9V),
data-collection device for the DCP. It automatically
displays and records the penetration per blow,
correlated values, depth, mm/blow, cumulative
mm/blow, and cumulative blow/inch in SI and
English. It also displays penetration rate correlations
to CBR (California Bearing Ratio), Bearing capacity in
Kips per square foot, and unconfined compression test.
The data is recorded on an USB flash drive along with
the test information entered by the operator and
date/time for each test. The USB flash drive enables
quick upload of data. Shipping: 48" x 7" x 7", 5 lbs.
