DIGITAL WEBSTER HARDNESS TESTER
1. Application
1.To determine whether the workpiece has been heat treated, to check the effect of heat treatment
2. To determine whether the workpiece has an improper alloy processing
3. To test the workpiece which is inconvenience to the laboratory( too long, overweight workpiece or assembly parts)
4.Used for production inspection, acceptance inspection and quality supervision and inspection
5. Mainly used for measuring aluminum alloy (1100~7075 Series) hardness
2. Technical Parameters:
Hardness Measuring range: 0 ~ 20HW
(aluminum and aluminum alloy 20 ~ 110HRE)(Copper Alloy 60 ~ 90 HRF)
Measuring accuracy:±0.5HW
Display resolution:0.1HW
3.Operating Principle
Digital display Webster hardness tester is a kind of indentation hardness tester. Under certain pressure, the pressure needle into the sample surface, the pressure is inversely proportional to the depth and material hardness. Webster's hardness with symbol HW said.
For range of samples, after strength numerical still shows 20.0; For the low range of sample, numerical display strength after 00.0.
