Overview
HS-O digital O-type rubber hardness gauge is suitable for Hardness measurement of soft rubber, thermal plasticity resilience, extremely soft plastics and thermal plasticity plastics, medium density Spinning & weaving coils, especially recommended for hardness of materials < 20 HDO occasions. The hardness gauge can be used in hand or with a fixed load test bench. Equipped with special host computer software, it can realize data storage, analysis, export, query and printing functions, and is widely used in mass testing, physical experiments, engineering testing and other fields. This hardness gauge is implemented in accordance with the American ASTM D2240 standard and corresponds to the Type O hardness gauge.
Features
1. LCD display, intuitive reading.
2. With real-time mode, it can display real-time changes in Hardness value.
3. With peak mode, Hardness peak can be recorded during the test.
4. With automatic timing mode, the force holding time of the test process can be set (such as 3 seconds for vulcanized rubber and 15 seconds for thermal plasticity rubber).
5. With average mode, the number of tests can be set.
6. Equipped with automatic shutdown function.
7. Equipped with Chinese WINDOWS interface host computer software, rich in functions:
- The test results are displayed with multiple coordinates: real-time Hardness value - time, Hardness peak - number of times, and timed Hardness value - number of times.
- With qualified judgment function, it can be automatically judged according to the preset Standard value range.
- Test data and Linear dispersion are automatically stored to the computer with unlimited storage.
Test data can be queried and exported to Excel format.
Test reports can be prepared, generated, and printed according to user requirements.
Principle
This hardness gauge is performed in accordance with the American ASTM D2240 standard and corresponds to the Type O hardness gauge. Hardness value of a material is characterized by measurement of the depth or deformation of the indenter pressed into the material under the action of a specific test force.
Applications
Soft Rubber, Thermal plasticity resilience, Extremely Soft Plastics and Thermal plasticity Plastics, Medium density Spinning & weaving Coils Hardness measurement, mass testing, physical experiments, engineering tests
Standards
American ASTM D2240 standard
Steps
1. Choose handheld or matching fixed-load test bench according to measurement needs.
2. After starting, set the corresponding force holding time in the automatic timing mode according to the material type (such as vulcanized rubber or thermal plasticity rubber).
3. Select Measurement mode (such as real-time mode, peak mode, or average mode).
4. Press the hardness gauge head vertically to the surface of the tested sample.
5. Read and record the Hardness value (real-time value, peak value, or average value) displayed on the LCD screen.
6. If you need data management, you can connect to the computer through the host computer software for Data storage, analysis, export, query and printing reports.
Notice
- This hardness gauge is suitable for the measurement of hardness of materials < 20 HDO and is not recommended for hard materials beyond this range.
- During measurement, ensure that the indenter acts vertically on the surface of the sample to ensure measurement accuracy.
When using automatic timing mode, set the force hold time correctly according to material standards (e.g. ASTM D2240) or process requirements.
When using the matching fixed-load test bench, ensure that the bench is firmly installed.
When connecting to the host computer software, please ensure that the computer system is compatible (Chinese WINDOWS interface).
- Maintain and calibrate instruments regularly to ensure Measurement accuracy.
