The YDRZ-4L soil bulk density tester is a newly developed product “YDRZ-4L” sand filling method bulk density tester according to the requirements of the national standard GBT50123-99.
The soil bulk density tester is also called ring knife method bulk density tester, soil bulk density tester, suitable for on-site determination of the density of coarse-grained soil, has a chassis, sand filling funnel, bulk density bottle, valve structure is strong and durable, made of stainless steel.
The volume of the sand container has been rigorously calculated and designed, and the calibration error of the electronic balance is within 5g, which provides reliable data for the experiment. The sand filling funnel is 135mm in height and the sand container has a volume of 4L. The product also has a series of products (plastic, Iron sheet) to choose from.
Principle of the instrument
The soil bulk density tester adopts the ring knife method, which uses a guide rod and a drop hammer to press the ring knife naturally without affecting the original structure of the soil.
Instrument Configuration
2 ring cutters, 2 ring cutter press blocks, 1 directional cylinder, 1 guide rod, 1 drop hammer, 2 knobs
