Instrument Introduction:

YDRZ-4L Soil Bulk Density TesterAccording to the national standard GBT50123-99, a new product called "YDRZ-4L" sand filling method bulk density tester has been developed. This soil bulk density meter is suitable for on-site measurement of the density of coarse-grained soil. It consists of a chassis, a sand filling funnel, a bulk density bottle, and a valve. The structure is sturdy and durable, and is made of stainless steel material. The capacity of the sand bottle has been strictly calculated and designed, and calibrated with an electronic balance within a range of 5g to provide reliable data for experiments. The sand filling funnel is 135mm high, and the sand bottle capacity is 4L. There are also a series of products (plastic, iron sheet) to choose from.

Principle of Soil Bulk Density Tester:

Adopting the ring knife method, using a guide rod and a falling hammer to apply natural pressure to the ring knife without affecting the original structure of the soil.

to configure:

2 ring knives, 2 ring knife pressure blocks, 1 directional cylinder, 1 guide rod, 1 drop hammer, 2 knobs
