Dial pocket penetrometers
Standards:
ASTM D2573
Description:
They are suitable for in-situ or indoor measurement of the liquid index of general clayey soil, soft soil, compacted soil, red clay and loess and rough estimation of the bearing capacity of soil. Compared with hand identification, micro penetrometer can improve the description accuracy of the soil to be measured and reduce human error.
There are three ranges
DPP-3.0, suitable for soft soil, small range
DPP-4.0, suitable for hard soil, large range
DPP-5.0, suitable for soft soil, micro range
Soil Testing Equipment
Features:
Portable instrument
Different models can obtain different measuring ranges and test accuracy
Precision integrated
All metal structure, durable and cost-effective
Convenient to carry and better protected
