Overview
JMHVS-30AT precision digital display Vickers Hardness Tester (head mobile) is a new generation product with a unique head down-pressing design and a sturdy structure. It combines precision machinery and photoelectric technology, uses a fully closed-loop Control system, and uses a pressure sensor as a feedback unit to ensure accurate and stable testing.
Features
1. Measurement light source strength can be adjusted by pressing the button.
2. With a mobile head structure, linear slide guide, using T-screw and High Accuracy motor drive.
3. Fix the stage to reduce the coaxiality error caused by the up and down movement of the screw.
4. Crane measurement is more stable.
5. The working platform has a large space, which can realize large-scale measurement and is suitable for replacing large-scale working platforms.
6. Unique Closed Loop Control system, hardness testing is faster and more accurate.
7. Automatic conversion of indenter and objective lens.
8. And can preset the test force holding time.
9. Hardness value conversion table built into the software.
10. Easy to use, Measurement accuracy.
11. The hardness gauge can also prepare a photographic device according to the special requirements of the user, which can shoot the metallographic structure of the measured material and the material.
Principle
The hardness gauge adopts a full closed-loop Control system, and the test force is fed back in real time through the pressure sensor to realize automatic loading and unloading of the test force. During the test, the indenter is pressed into the surface of the sample under the preset test force, removed after a certain period of time, and then automatically switches to the objective lens, observes and measures the diagonal length of the Cong through the Microscope, and calculates and displays the Vickers or Knoop Hardness value in combination with the built-in conversion table.
Applications
Steel, non-ferrous metals, IC chips, thin plastics, metal foils, platings, coatings, surface hardening layer, laminated metals, heat treatment effect, carburizing layer hardening depth, cemented carbide, ceramics, sheets, Eletroplating, micro-targets, welding joints, deposition layers
Standards
EN ISO 6507、EN ISO 6506、ASTM E-384、ASTM E-10-08、ASTM E-384 GB/T231.2、JJG150
Steps
1. Place the specimen on the stage and level it using horizontal adjustment screws.
2. Select the required test force, ruler and load holding time through the Touchscreen.
3. Start the test, and the equipment will automatically complete the pressure head down, load, unloading and pressure head/objective lens switching.
4. Observe the Cedar through the micrometer eyepiece, or directly measure the diagonal length of the Cedar on the screen.
5. The device automatically calculates and displays the Hardness value.
Notice
• Please ensure that the equipment is placed horizontally before use.
Do not exceed the maximum height (210mm) and width (150mm) of the specimen.
• Operating temperature (10~ 38 ℃) and power supply (AC220V/50Hz).
When replacing a light bulb or fuse, use spare parts and ensure that the device is powered off.
• Regularly calibrated using standard Hardness Blocks to ensure Measurement accuracy.
• Please follow the product instruction manual when operating and pay attention to safety.
