Compressive Strength Tester

Used for testing the compressive strength test of cartons and other packing containers and transport packages.

Product features

With high-precision force measuring sensor, the accuracy of the factory is controlled at <0.5%, which is better than the ISO standard of + 1%.

Fully automatic test, the device has the function of displaying test data, memory storage, analysis, statistical processing and printing test report, and it is easy to operate. The preset test speed and the return speed, as well as the free adjustment of the upper plate position, make the test more rapid and efficient.

The force sensor is positioned above the upper platen and the user or measurement and calibration Department (third party) positions the standard sensor between the upper and lower platen

The calibration error of the instrument can be easily calibrated by performing calibration operations.

Safety protection measures:

Measurement and control system, pressure value, overload protection;

Power off, automatic locking, transmission protection;

The sensor pressure value is reset automatically and zero is displayed;

The test is completed and automatically returned to its original position;

The preset test speed and return speed make the test faster and more efficient.

Test description

Place the test sample on the top of the test machine and the center of the lower platen. Then choose one of the test methods:

Compression test: set the test speed and press the test speed until the test sample is crushed;

Setting test: setting load value or displacement value and pressing to a predetermined load value or displacement value;

Stacking test: setting a predetermined load and time, applying a predetermined load until the test sample is damaged or until a predetermined time.

Note: it is not recommended to compare the results at other speeds such as 12.5mm/min + 2.5 mm/min and 10mm/min + 3mm/min speed.

For certain packages, such as metal drums and wooden cases, a lower speed may be needed to prevent maximum load from exceeding a predetermined load value.
