ZL-1125A Soil Hardness Tester
Ⅰ Function：
The Soil hardness is directly measure the soil hardness by the theoretical value Kg/Cm2 of the pressure gauge.
It is very convenient and accurate for this soil hard meter to investigate and study the soil permeability, aeration and soil properties of large machinery operations.
Ⅱ Features：
This instrument is mainly used for rapid determination of the soil hardness, with very intuitive test results. Measure the soil wedging pressure to understand the tightness of soil at different depths.
Ⅲ Specifications and Parameters：
Indicative scope of hardness: • 0 ～40 mm， • 0～500 Kg/Cm2
Outline dimension:275mmX76mmX50mm.
Ⅴ Determination Method:
1) Firstly level the soil surface to be measured and then insert the whole of cutting-edge part of this device into the soil until the part of (opening).
2) Vertically pull out the soil hardmeter clockwise and read out the indicative hardness values from the meter.
3) After reading out the measurement values, rotate the knob of the driven pin to return to zero of the reading of the indicating meter.
4) If there are soils attached within the interior of the side, the measurement values will be incorrect; at this time, please rotate the (opening) part counter-clockwise, take off this round sleeve. After cleaning, rotate to a fixed position, and carry out measurement again.
