Soil Hardness Meter adopts theoretical value of pressure gauge Kg/cm²,directly measures soil hardness. For soil permeability, aeration and soil properties survey research. It's very convenient and accurate to use this instrument.
1. Level the measuring soil surface, 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/cm²
High-precision and high-resolution: large screen LCD display, with backlight function (backlight for night use), and positive, inverted reverse function of digitals on the screen.
Has a battery capacity display: divide into 3, 2 and 1 grids. If too low electricity, the instrument will automatically shut down.
Gravity acceleration setting function: users can input the exact value of gravity acceleration at their discretion to allow the test more precise.
Peak value maintaining function: maintain the peak value display until zero adjustment manually.
Automatic peak function: Maintain to display the peak values for 2 s before automatically elimination.
Large memory storage function: can store 896 test values.
Data output function: data can be input in the computer for various analyses through data links.
Auto-off time setting: with automatic off-time setting, 10min-90 min automatic shutdown can be set.
High quality charging power: 100-240V of charging voltage can be available.
Maximum load: 100Kg (Kg and N can be switched automatically).
Power: charging power supply:220V/AC;Continuous operating time of battery:6~8 hours
Stability: temperature drift :0.2uV/ºC(0-60ºC);Null drift:≤ 0.1%/8 hours /FS..
Calibration range: full-scale calibration.
Ambient humidity: ≤ 80%.
Power supply mode:5 nickel cyanogen battery /220V AC charge 4~6hour.
