The Pap Hardness Tester is mainly used to test aluminum and aluminum alloys. The Webster Hardness Tester is mainly used to test aluminum alloy profiles, plates and pipes. The Pap Hardness Tester should be used to test pure aluminum, softer aluminum alloys, ultra-thick aluminum alloys, aluminum alloy bars and assembled aluminum alloy products (such as aluminum alloy doors and windows, fire ladders, etc.), and is also used to test glass fiber reinforced plastics (glass fiber reinforced plastics), hard plastics, etc. The improved version of the Pap Hardness Tester can be used for softer plastics, very soft metals, leather, rubber, etc.
A lightweight indentation Hardness Tester;
Through anodizing treatment, wear-resistant and rust-free, comfortable feel;
Calibration at any time, one-handed operation, no experience required, in any occasion, as long as it is within reach, it can be tested;
Wide measurement range, measurable thickness as low as 1mm, from very soft pure aluminum to particularly hard aluminum alloy can be tested, the effective measurement range is equivalent to Brinell hardness 25~ 135HBW;
Wide range of applications;
High sensitivity. The instrument has 100 scales, and the sensitivity is much higher than that of the Webster Hardness Tester commonly used in the aluminum alloy industry;
No support required. It can be tested by touching only one side of the sample, without moving or supporting the sample, and is suitable for oversized and ultra-thick workpieces and assemblies;
Conversion is convenient. The hardness values of Brinell, Rockwell, Vickers, and Wechsler can be obtained through the conversion table;
Aluminum and aluminum alloys, copper and copper alloys, glass fiber reinforced plastic, hard plastics, etc. Its improved version can be used to test ultra-soft metals such as lead and tin and soft plastics, rubber, felt, leather, etc
