Soil Hardness Tester adopts theoretical value of pressure gauge--kg/cm2 to test the wedging resistance of soil and get the soil hardness value directly. Thus, the tightness degree of soil with different depth can be known. The instrument has the advantage of fast testing speed and visualized testing results. For soil permeability, aeration and other soil properties survey research, it’s very convenient and accurate using the tester.

Test method

1. Level themeasuring soil surfacce,then insert top part of instrument into the soil until (opening)part.

2. Vertically pull out the soil hardness meter and read the hardness indicating value of the meter.After finished reading the measured value ,drive rotary-knob,make the indicating meter to zero.

3. Soil attached to the inside of measuring head will make the measurements incorrect.Please clockwise rotate(opening) part ,take down round sleeve,rotate to the fixed position after cleaning up,then can measure again.

4. Hardness indication range:0-40mm,0-500kg/cm^2.
