Automatic Residual Indentation Tester

This test equipment is used to determine the residual sag, which is the difference in sag after a constant load is applied and removed from an elastic or flaky floor coating. The effect of the load is evaluated by comparing the initial thickness to the thickness difference after unloading, with the thickness measurement including the initial value before the load is applied and the final value after a recovery period. The sample is subjected to static compression at a specified load, and the test result is determined by comparing the thickness change before and after loading.
