Description

The compact two-spindle Crush Tester disposes of a built-on touchscreen and separate start and stop buttons. The respective test programs are to be selected on the display. After pre-selection of the desired test program, the test plates automatically go to their respective initial position. A safety protection (comprising an especially designed spring set) helps prevent damage to the force sensor by accidental operation. Various sample holders and sample preparation devices are at your disposal for the different test modes and can be ordered according to your needs. If desired, the instrument can be delivered with a device for 4-point bending tests instead of pressure plates.

Test description

By use of the touchscreen, the operator chooses the desired test program. The plates automatically take the right initial position. Prepared samples are placed between the plates (together with a sample holder, if required). The operator pushes the start button; The moving platen closes onto the sample at a preset speed, until the end of the measurement is reached. According to the test, this can be a preset breaking criteria or a preset distance. Values and graphs are displayed while the plates return to their initial position. The instrument is ready for the next test. A simple key press can change the test modes changed in the main menu.
