Webster Hardness Tester
The Webster hardness tester is an important tool for measuring the hardness of metals. It is widely used in hardness testing in industrial production and metal processing due to its accurate measurement method and convenient operation. Hardness measurement is a key link in quality control, because the hardness of metal materials not only reflects their strength and wear resistance, but also directly affects processing performance and service life.

How does a Webster hardness tester work?
The work principle of the Webster hardness tester is to press a steel indenter of a specified shape into the surface of the sample under a certain test force, and use the depth of the indenter to indicate the hardness of the material. The indentation depth of 0.0125mm (generally directly approximated to 0.01mm in actual use) is defined as a Webster hardness unit, represented by HW. The hardness of the material is inversely proportional to the indentation depth. The shallower the indentation, the higher the hardness, and vice versa.
Calculation formula: HW=20-L/0.0125
In the formula, "HW" represents the Webster hardness symbol, "L" represents the depth of the indenter into the sample, in millimeters (mm), and "0.0125" is the specified value.
Based on the Webster hardness measurement principle detection, the Linshang digital Webster hardness tester adopts the eddy current induction principle measurement technology to measure the distance between the indenter and the coil, thereby inversely calculating the depth of the indenter into the material being tested. Eddy current technology can sensitively capture tiny physical changes through electromagnetic induction, and has higher repeatability and test accuracy.

Comfortable grip
The body of the instrument is made of forged aluminium alloy material with anodic oxidation treatment, comfortable to hold, wear and pollution resistant.
Providing standard hardness block
Providing standard Webster hardness block, in strict accordance with the metrological verification procedures for the degree, and its surface roughness and flatness in line with the requirements of the regulations.
Main Application
1) Die cavity of molds
2) Bearings and other parts
3) Failure analysis of pressure vessel, steam generator and other equipment
4) Heavy work piece
5) The installed machinery and permanently assembled parts.
6) Testing surface of a small hollow space
7) Material identification in the warehouse of metallic materials
8) Rapid testing in large range and multi-measuring areas for large-scale work piece
What are the precautions for using a Webster hardness tester?
a. Try to use as little air pressure as possible on the instrument to avoid damaging the indenter too quickly, which will affect the stability of the instrument and the accuracy of the data.
b. The surface of the sample should be clean. Surface dirt or coating will affect the measurement accuracy.
c. When measuring, the distance between any two indentations should not be less than 6mm, and the distance between the center of the indentation and the edge of the object being measured should not be less than 5mm.
d. When measuring, you need to press it hard to the bottom at one time. Do not press it slowly.
e. The measurement accuracy will be reduced for hardness below 4HWA or above 17HWA.
