Sponge foam indentation hardness tester

Sponge indentation hardness stress tester, sponge indentation hardness tester, foam indentation hardness tester Purpose:

This machine is used to measure the indentation hardness of porous elastic materials. The polyurethane sponge foam sample can be tested according to the national standard, and the indentation hardness of sponge, foam and other materials can be accurately measured. It can also be used for the production of seat foam

(such as backrest, seat cushion foam, etc.) to measure the specified indentation hardness and accurately measure the indentation hardness of each foam part of the seat.

The principle of sponge indentation hardness stress tester, sponge indentation hardness tester, and foam indentation hardness tester: the sponge foam compression stress test places the sample between the upper and lower platens, and the upper platen compresses a certain size of sample downward at the specified speed to the concavity specified in Method A (Method B, Method C) required by the national standard, the load cell on it will feedback the induced pressure to the controller for processing and display, so as to measure the indentation hardness of sponge, foam and other materials.

3、 Functional Features

1. Auto reset: After the computer receives the instruction to start the experiment, the system automatically resets to zero.

2. Automatic return: After the sample breaks, it automatically returns to its initial position.

3. Automatic shifting: Depending on the load, different gears can be switched to ensure measurement accuracy.

4. Change speed: This machine can arbitrarily change the test speed according to different samples.

5. Indication verification: The system can achieve accurate calibration of force values.

6. Control method: Test force, test speed, displacement, strain and other test methods can be selected according to the needs of the experiment.

7. Multi purpose of one machine: Equipped with sensors of different specifications, it can achieve multi purpose of one machine.

8. Curve traversal: After the experiment is completed, you can use the mouse to find the force values and deformation data of the test curve point by point and analyze them.

9. Display: Dynamic display of data and curve testing process.

10. Result: The experimental results can be accessed and the data curve can be analyzed.

11. Limit: It has programmable and mechanical limit.

12. Overload: Automatic shutdown when the load exceeds the rated value.
