Description
Summary:
Automatic smoothness and surface roughness tester is used for testing the smoothness of paper and paperboard; it is ideal testing equipment for paper making, packaging, printing, commodity inspection, scientific research and other departments.
Standard:
ISO 5627, GB/ T456: Paper and board – Determination of smoothness (Bekk Method)
QB/T 1665: Paper and board – Tester of smoothness
Application:
Measure specimen: This smoothness tester is used for testing high smoothness paper and
paperboard. It should not be used for testing materials with a thickness of more than 0.5mm or paper or paperboard with a high permeability, because the amount of air through the sample may cause unreal results.
Free conversion of gear A, B, C, and ensure that the sample is pre-pressed for 60 seconds according to the national standard.Added quick test mode, greatly reducing test time.
