Product Description

Soil portable hardness tester adopts a theoretical value of pressure gauge Kg/cm², to measure soil hardness directly. For Soil permeability, aeration, and soil properties survey research.

Hardness indication range: 0-40mm, 0-500kg/cm2

 

Test method:

Ø   Level the measuring soil surface, and insert the pinpoint of the meter into the soil until (opening) part.
Ø   Vertically pull out the soil hardness meter and read the hardness indicating value.
Ø  After finished reading the measured value, drive rotary-knob, make the indicating meter to zero.
Ø   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, and then can measure again.
