The paper smoothness tester (mercury free) (hereinafter referred to as the smoothness tester) meets the technical requirements and testing methods of international standards such as ISO5627 "Determination of Paper and Boardboard Smoothness (Buick Method)" and QB/T1665 "Paper and Boardboard Smoothness Tester". It is an essential instrument for various high smoothness paper testing. This smoothing instrument is used for testing high smoothness paper and cardboard, and should not be used for testing materials with a thickness of 0.5 mm or above or paper or cardboard with high air permeability, as the amount of air passing through the sample can cause unrealistic results.
Instrument features:
1. BST Smoothness Tester is an intelligent paper and paperboard smoothness performance testing instrument designed and developed based on the working principle of the universal Buick Smoothness Tester.
2. This instrument is used for measuring the surface smoothness of paper and cardboard, and is an ideal testing equipment for departments such as papermaking, packaging, printing, commercial inspection, and scientific research.
3. This instrument adopts high-performance microcomputers, high-precision sensors, German * oil-free vacuum pumps, and professionally manufactured vacuum volume blocks and solenoid valves to achieve mercury free rapid measurement.
Compliant with standards:
ISO5627 "Determination of smoothness of paper and paperboard (Buick method)"
QB/T1665 "Paper and Board Smoothing Instrument"
