58-05 Bekk Smoothness Tester

The Automatic Bekk Smoothness Tester is a microprocessor-controlled instrument for the determination of smoothness of paper and board according to the Bekk Method.This air leak smoothness test is useful for very smooth surfaces, for example, coated label papers, coated free sheet, or other very smooth papers.            








An innovative new feature is the Estimated Test Result. It was implemented to save the operator time when setting up a new test series and choosing the pressure interval and volume setting but also to save the operator time when doing a quick single test to see what the value of the paper approx. will be. The ETR value is calculated after the test has been started (50.66 kPa) based on the rate of rise of pressure. After 10 seconds the ETR value is displayed. During the test the ETR value is constantly re-calculated and updated until the ETR value at 48.00 kPa is the same as the final test result.

Estimated Test Result:  Approx. 10 seconds
