? ? ? ? ? Design standard:?ISO 5627 GB/T 456 GB/T 1665

? ? ? ? ? Uses:

ISO 5627 LCD Screen 0.1 Prescision Paper Bekk Smoothness Tester With Vacuum pump With Vacuum pump is a new type of test developed by our company according tothe specification of international standard. Bekk Smoothness Tester ?mainly test the smoothness off the paper or cardboard (by Bekk method).

? ? ? ? ? Features:

It\'s?time in seconds which under a defined pressure differential is required to draw a definite quantity of air at atmospheric pressure between the surface of the test piece and a ring-shaped plane surface under specified conditions of contact. The smoothness of a wide range of papers and boards may be measured by this method and it is especially recommended for smooth papers and boards. However , for very smooth samples, measurement times may be impractically long.

? ? ? ? ? Characteristics:

1. Oil-free vacuum pump: Uses the imported vacuum pumps, it can work without oil. The equipment is oil-free and pollution-free
2.?Rapid measurement: Choose small volume to measure, the measuring time is only one-tenth of large volume. In this way users can save much measuring time and realize the rapid measurement
3. Automatic identification and switch of cavity volume: The size of cavity volume in instrument has the function of automatic identification and switch, it can measure and automatic identification
4. Automatic calculation at both sides of gap: Instrument can measure the positive and negative sides of smoothness according to the requirements
