W-B75, B-series Webster hardness testers

Description

Product Introduction:

The W‑B75/B-type Webster hardness tester is a single‑hand‑operated, portable device that enables rapid on‑site hardness testing of materials such as soft brass. It offers quick, simple measurements with a single insertion, and the hardness value is read directly.

Main uses and scope of application:

1. Determine whether the workpiece has undergone heat treatment and inspect the effectiveness of the heat treatment.

2. Determine whether the workpiece is made of an unsuitable alloy.

3. Testing of excessively long, heavy workpieces or assembled components that cannot be conveniently transported to the laboratory.

4. Used for production inspection, acceptance inspection, and quality supervision inspection.

Key functions and features:

1. The Vickers hardness tester is suitable for testing profiles, tubes, and sheets, and is particularly well suited for rapid, non-destructive conformity checks of product hardness at the production site, sales outlet, or construction site.

2. Standard hardness blocks have been tested using a standard hardness tester;

3. The Vickers hardness value can be converted into commonly used values for Vickers, Rockwell, and Brinell hardness, as well as tensile strength.

Technical Specifications:

1. Measuring range: 0–20 HW
2. Accuracy: 0.5 HW

3. Measurement range: equivalent to Rockwell hardness of 63–105 HRF;
