Sponge Foam Compression Hardness Tester Force Value Test Machine
This machine is used to determine the concave hardness of porous
elastic material. The foam samples of polyurethane sponge can be
tested according to the national standard, and the compressive
hardness of such materials as sponge and foam can be accurately
measured. It can also be used to measure the compression hardness
of seat foam (such as backrest, cushion foam, etc.)
PRINCIPLES:
When the sponge foam compression stress test places the specimen
between the upper and lower pressure plates, and the upper pressure
plate compresses the specimen of a certain size down at a specified
speed to the concavity specified in the A method (B method, C
method) required by the national standard, the load element on the
specimen will feedback the induced pressure to the controller for
processing and display, thus measuring the compression hardness of
the specimen such as sponge and foam.

Functional characteristics
1. automatic zeroing: the system automatically clears after the
computer receives the test start instruction.
2. automatic return: after the specimen breaks, it automatically
returns to the initial position.
3. automatic shift: according to the size of the load, different
gear can be switched to ensure the measurement accuracy.
4. change speed: this machine can change the test speed arbitrarily
according to different samples.
5. indication check: the system can realize accurate calibration of
force value.
6. control method: according to the test needs, the test force,
test speed, displacement, strain and other test methods can be
selected.
7. one machine multi-purpose: equipped with different
specifications of sensors, can achieve one machine multi-purpose.
8. curve traversal: after the test is completed, the force value
and deformation data of the test curve point by point can be found
arbitrarily by mouse and analyzed.
9. display: data and curve test process dynamic display.
10. Results: Test results are accessible and data curves are
analysed.
11. Limitations: programmed and mechanical.
12. Overload: Automatic shutdown when the load exceeds the rating.
