Overview
W-B75 series Webster Hardness Tester is a small Portable instrument based on the mechanical press-in Measurement principle, suitable for fast and easy measurement of copper alloy Hardness, especially for other instruments can not or inconvenient measurement of the shape. This series does not require sampling, easy to operate, is widely used in Aluminum profile industry, doors and windows curtain wall enterprises, engineering Quality control and technical supervision departments, to meet most of the production quality control and qualified determination of the detection needs.
Features
1. New materials, new technology manufacturing, Hardness, long life, good interchangeability.
2. High-strength pointer, not easy to bend and deform.
3. High strength, high toughness window glass, anti-Impact.
4. Forged aluminum alloy handle, anodic oxidation treatment, beautiful, wear-resistant, pollution-resistant.
5. Equipped with standard Wechsler Hardness block and test report verified by standard Hardness machine.
6. Small size, light weight, can be operated with one hand, portable and fast.
7. The testing process does not require sampling and can be nondestructive testing, especially suitable for production sites.
8. There are no strict restrictions on the shape of the material to be tested, and it is suitable for copper alloys of various shapes.
9. Equipped with calibrating sleeve to reduce the error of multiple full scale calibrating.
10. Simple operation, human operation has little impact on measurement results.
11. The reading is convenient and can be easily converted to other Hardness values.
Principle
The hardness gauge is based on the Measurement principle of mechanical press-in, formed by the crimping needle on the surface of the material, the measurement of the Wechsler Hardness value of the material according to the depth of the crimson or related mechanical structure indication.
Applications
Evaluate whether copper alloy materials have heat treatment and heat treatment effect, determine whether the material mechanical performance is qualified, determine whether the material alloy composition is qualified, control the production process and product factory acceptance, on-site inspection of too long and too heavy workpieces or accessories, Aluminum profile industry, door and window curtain wall enterprises, Engineering Quality control, Technical supervision department
Standards
check standard block
Steps
1. Manual full scale calibrating.
2. Aim the instrument crimp at the surface of the material to be tested.
3. Manually apply measurement force for measurement.
4. Read Hardness value through Mechanical Display mode.
Notice
* The instrument should be used in a clean, vibration-free environment.
* There should be no corrosion medium around.
Universal type (W-B75) is suitable for testing profiles, plates with a thickness of less than 6mm, and pipes with an inner diameter of more than 10mm.
