Overview
W-20A Webster Hardness Tester is a model of the W-20 series under the PORUIKE brand. It is a small Portable instrument based on the mechanical press-in Measurement principle. It is suitable for fast and convenient measurement of Aluminum profile Hardness, especially for other instruments that cannot or are inconvenient for measurement, such as extruded Aluminum profile, pipe, plate, etc. The measurement process does not require sampling, and the operation skills are not high. The product is widely used in the Aluminum profile industry, door and window curtain wall enterprises, engineering Quality control and technical supervision departments to meet the testing needs of production quality control and qualification determination.
Features
1. New materials, new technology manufacturing, Hardness, long life, good interchangeability.
2. High-strength pointers are not prone to bending and deformation due to long-term use or incorrect operation.
3. High-strength, high-toughness window glass is not easy to break after being impacted.
4. Forged aluminum alloy material, anodic oxidation on the handle, beautiful, wear-resistant, pollution-resistant.
5. The standard Wechsler Hardness block verified by the standard Hardness machine, with a test report.
6. Portable instrument, small size, light weight, can be operated with one hand, can quickly measure the Hardness of aluminum alloy and other materials.
7. The testing process does not require sampling, and can nondestructive test hardness of materials. Especially suitable for rapid Hardness testing of materials at the production site.
8. There are no strict restrictions on the shape of the material to be tested, and it can be applied to detect different shapes of Aluminum profiles.
9. Equipped with calibrating sleeve to solve the problem of calibrating error due to multiple full scale calibrating.
10. The operation is simple, and the operation skills have no impact on the reading.
11. Easy to learn, no difficult skills operation requirements, human operation has little impact on the measurement results.
12. The reading is convenient and can be easily converted to other Hardness values.
Principle
The W-20A Webster Hardness Tester is based on the Measurement principle of mechanical indentation. Hardness is measured by forming a Crowd on the surface of the material with a crimp. The instrument is calibrated with a standard specimen using manual measurement and mechanical Display mode.
Applications
Evaluate whether the aluminum alloy material has heat treatment, check the heat treatment effect, determine whether the material mechanical performance is qualified, judge whether the aluminum alloy material is made of inappropriate alloy processing, determine whether the material alloy composition is qualified, determine the Wechsler Hardness qualification value of the product to control the production process and product factory acceptance, on-site testing of long and heavy workpieces or accessories that are not convenient for sampling or sent to the laboratory, Aluminum profile industry, door and window curtain wall enterprises, Engineering Quality control and technical supervision departments
Steps
1. Before use, calibrate by standard Hardness block or equipped calibrating sleeve.
2. Align the instrument crimp vertically with the surface of the material to be tested.
3. Manually apply pressure for measurement.
4. Read the Hardness value displayed on the mechanical dial.
5. Wechsler Hardness values can be converted to Miscellaneous Hardness values (e.g. HRE, HV) as required.
Notice
* The instrument should be used in a clean, vibration-free environment without corrosion medium.
