Note1: The parameters in the table are measured by professional operator in Labthink laboratory according to relative requirements for laboratory standard conditions.
Note2: DataShieldTM provides safe and reliable data application support. Multiple Labthink instruments can share one single DataShieldTM system which can be purchase as required.
Note3: Test pressure and contact area can be selected for paper or film. There are two options for test pressure for paper, i.e. 100kPa (standard) and 50kPa(optional). For other test pressure and contact area or curved pressure foot, customizations are available.
The pre-conditioned specimen is placed on a flat test plane, the pressure foot which is paralleled to the test plane will drop down on the upper surface of the specimen with certain pressure applied on. The displacement sensor with the pressure foot will detect the space between the upper and lower surface of the specimen, which is the thickness of the specimen.
