APPLICATIONS& TEST PURPOSE
Mattress roller durability tester combines the loading device (roll) with a hardness measuring device. Thus, firmness test can be carried out according to ASTM F1566 or EN 1957, without the need for a rearrangement of the specimen, which would falsify the measured values. It can also display height change by servo measuring system.
After simply loosening the front frame reinforcement the specimen can be inserted into a flexible test base plate. This makes the testing device very effective and space-saving.
Software allows for a flexible parameter entry, the execution of different testing procedures, a graphical representation of measured values, test evaluation, and logging. Then the pre-set number of cycles is reached, the test is ended automatically.
