Overview
AW-B75 Webster Hardness Tester is a Portable hardness testing instrument under the AMITTARI brand. It is specially designed for rapid on-site detection of hardness of materials such as hard or semi-hard brass and superhard aluminum alloys. It is easy to operate, and the hardness value can be directly read by simply sticking the instrument on the sample. It is especially suitable for rapid, non-destructive piece-by-piece qualification inspection of large quantities of products on production, sales or construction sites.
Features
1. Press needle: New material, new process manufacturing, high hardness, long life, good interchangeability.
2. Pointer: high-strength design, long-term use or wrong operation is not easy to bend and deform.
3. Handle: Forged material, surface anodic oxidation treatment, beautiful, wear-resistant, pollution-resistant.
4. Hardness block: Standard hardness block is tested by standard hardness machine to ensure the accuracy of calibrating.
5. High mass: fine parts processing, precision machine assembly, strict mass inspection.
6. Good stability: full point stability, correction point stability, reliable measurement results.
Principle
The Webster Hardness Tester forms Cedars by pressing a pin of a specific shape into the surface of the material under the action of a standard spring force. The instrument measures the depth or related dimensions of the Cedars and converts them to the corresponding hardness value, which is displayed directly on the dial, enabling fast, non-destructive hardness testing.
Applications
On-site rapid hardness testing of hard or semi-hard brass, super hard aluminum alloy and other materials
Standards
The data did not mention specific compliance criteria.
Steps
Ensure that the sample size meets the requirements (Film thickness 0.6-6 mm, inner diameter > 10mm).
2. Card the hardness gauge on the sample to be tested.
3. Read the hardness value directly from the instrument dial.
Notice
* Please ensure that the material under test is hard or semi-hard brass or super hard aluminum alloy.
* Please ensure that the sample size is within the allowable range of the instrument (Film thickness 0.6-6 mm, inner diameter > 10mm).
When operating, please follow the correct method of use to avoid undue external force on precision components such as pointers.
* Regularly calibrate the instrument with standard hardness blocks to ensure measurement accuracy.
Please note that the battery model is 2 * 1.5AAA to ensure sufficient power.
