soil hardness tester is the use of pressure gauge of the theoretical value Kg/Cm2, directly measure the soil hardness value.
Soil hardness meter instrument principle:
This soil hardness tester is the use of pressure gauge of the theoretical value Kg/Cm2, directly measure the soil hardness value.
For the permeability of soil, air permeability and large machine homework soil property investigation and study, using the soil hardness meter is very convenient accurate.
Technical parameters:
Soil hardness meter measurement methods:
1, first will want to measure soil surface leveling, and then use this device tip part all into soil, until (mouth) part.
2, vertical consequent pull out soil hardness tester, and from the list read hardness indicated value.
3, read the measuring value finished, please rotation driven needle knob, make the indicator to zero.
4, if side head internal adhesion soil, will make the measured value into is not correct, please anti clockwise (mouth) department, take down this circular sleeve, please clean up turn to the fixed position, can measure again.
5, hardness indication range: 0 ~ 40 mm; 0 ~ 500 Kg/Cm2
