PCE-HT-225A Roll Hardness Test Instrument
PCE-HT-225A is a roll hardness test instrument or paper roll test hammer, also called a roll rebound hammer or Swiss hammer, used for non-destructive measurements of surface hardness and compression strength. Suitable for use with rolled paper, concrete, rock and building materials, this manufacturer-calibrated manual rebound hammer is economical, practical and easy to use.
The quality of rolled paper is judged mainly on the basis of compressive strength, since compressive strength is directly responsible for the structural behavior and durability of rolled paper. For psi roll hardness measurement, download the chart to convert rebound value to psi. Optional test anvil to verify accuracy listed under accessories.
