Overview
The PORUIKE 934-1 Pap hardness gauge is a Portable Indentation hardness tester that presses a specimen under standard spring force with a specific indenter to determine Hardness at Cedric depth. It is easy to operate, no experience required, can be used in any position by hand, and the reading is displayed instantly on the dial. The hardness gauge has 100 scales, each scale represents 0.0076mm pressing depth. It is suitable for Hardness measurement of aluminum, aluminum alloy, soft metal, plastic, frp, composite, rubber, leather and other materials. It is a special instrument for mass certification, monitoring and Measurement testing.
Features
1. Easy to use: one-handed operation, high efficiency, can be used in any occasion.
2. Sensitivity: 100 scales, Sensitivity higher than Webster Hardness Tester.
3. Easy to test: no sampling, nondestructive testing hardness of materials.
4. Hardness Measurement range: from pure aluminum to super hard aluminum alloy can be tested, equivalent to brinell hardness 25~ 130HBW.
5. Measurement range: material thickness greater than 0.8mm can be tested.
6. No support required: It can be tested by touching only one side of the sample, and can test oversized, overly wide, and overthick materials and assembled aluminum alloy products.
7. Convenient conversion: It can be easily converted into Wechsler, Brinell, Rockwell, Vickers and other Hardness values.
8. High mass pressure needle: Hardness, long life and good interchangeability.
Principle
The PORUIKE 934-1 Pap hardness gauge uses the principle of the Crowd method. The instrument presses the surface of the measured material under the action of the standard spring force through the indenter of a specific geometry (26 ° frustum cone, the diameter of the cone surface is 0.176mm) to form a Crowd. The Hardness value is determined by measuring the depth of the Crowd and is immediately indicated by the pointer on the dial. Each scale corresponds to the depth of indentation of 0.0076mm.
Applications
Thick-walled aluminum alloy profiles, pure aluminum, softer aluminum alloy, super hard aluminum alloy, Aluminum Panel, aluminum rod, aluminum alloy castings, forgings, die castings, assembled aluminum alloy products (such as aluminum alloy doors and windows, curtain walls, fire ladders), FRP, hard plastics and other Non-metallic materials
Standards
GB/T3854-2005、ASTM B648-2000
Steps
Make sure that the thickness of the material under test is not less than 1mm, and the surface is smooth, clean, and free from mechanical damage.
2. Hold the hardness gauge and align the indenter vertically with the point to be measured.
3. Apply force smoothly to press the indenter into the sample.
4. Read the Hardness value indicated immediately by the pointer on the dial.
Notice
The thickness of the measured material should not be less than 1mm.
The surface of the specimen should be smooth, clean, free of mechanical damage, and can be lightly polished to remove scratches or coatings.
• Impact and sliding scraping should be avoided during measurement to avoid damage to the indenter.
• The instrument should be avoided in environments with strong vibration, moisture and corrosive gases.
