Working Principle
The basic principle is to use an impact body of certain weight impacts against the testing surface under certain test force, then measure the impacting velocity and the rebounding velocity of the impact body respectively when the spherically test tip is located 1mm above the testing surface.
The calculation formula is as follows:
HL×10000×VB/ VA
Where:
HL—— Leeb hardness value
VB—— Rebounding velocity of the impact body
VA—— Impacting velocity of the impact body
Working Conditions
Working temperature：- 10℃～＋50℃；
Storage temperature：-30℃～＋60℃
Relative humidity: ≤90％；
The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.
Instrument Features
Basic (single-point) calibration and multi-point calibration function for convert curve,to reduce the test error.
Hardness scales can to convert to HL,HRB, HRC,HRA, HV,HS,
Built-in Leeb hardness conversion function to converse HLD to HLC,HLG,HLDL,HLD+15,which is convenient for calibration and value conversion.
Preset up and low limit of hardness value , it will alarm automatically if out of range alarm, convenient for batch testings.
Chinese-English converting, menu operation, easy and convenient.
It can store 500 groups (impact times 32 ~ 1) hardness values, each data includes single testing value, average value, measurement date / time, impact direction, frequency, material, hardness and other information.
Two ordinary AA batteries, it can work for not less than 100 hours; automatic screen standby , automatic sleep, automatic shutdown and other power-saving features.
With field-portable mini-printers with Bluetooth communication, convenient to generate data reports
USB interface can do transmission measurements, value storage management, value statistical analysis ,printing the value report and batch setting the instrument parameters through the PC data-pro software, to meet the higher demand for quality sealed aluminum-magnesium alloy metal shell, compact, high portability, reliability, designed for harsh field environments, rugged, unique seal design allows it to resist wet , sand, dust, oil and other contaminants of harsh environments from the ocean to the desert
