Product Description

XHV-26BT Bendtsen Roughness Tester measures paper and cardboard surface roughness using the air leakage method.

The device use a metal ring with a defined measurement area, delivering a weak compressed air flow.

The amount of air that leaks indicates surface roughness – the more air leakage, the rougher the paper surface, meaning its smoothness is lower.

Test Standards

BS 4420, DIN53108, ISO8791-2, SCAN P21, SCAN P84, NEN2012,NFQ 03-076,APPITA1301.439
