E-850 Soil Assessment Cone Penetrometer
This is an easier to use, more reliable cone penetrometer than E-910 (see related items for description). It can be used to obtain in-situ bearing strengths that can be correlated with lab tests and is primarily intended for fine grained soils where the bearing strength can be taken for trafficability or for load bearing capacity. Two different area 30 degree cones are provided. One is used for CBR and the second for cone index testing.
In use the device is placed vertically on the surface to be tested with the operator standing square to and above the instrument. A steady force is than applied forcing the probe into the soil. Readings are taken from a graduated scale every 75mm in terms of CBR or Cone Index. Scale is graduated 0-15% CBR and 0-300 Cone Index.
The complete kit includes a cone index and CBR 30 degree cone, 4-150mm extension rods marked at 75mm, 2–spanner wrenches, head assembly with graduated scale and folding handle, carrying case and operating instructions. Weight including case is 5.5 lb (2.5kg).
Shipping Weight: 7 lb (3kg); 2 cu. ft.
E-850L Soil Assessment Cone Penetrometer With Back Light
This is same as E-850 except it includes a back light for easier viewing in sunlight.
