PN-BSTThe Bekk Smoothness Tester is an intelligent paper and paperboard surface smoothness performance testing instrument designed and developed based on the working principle of the internationally recognized Bekk smoothness tester, combined with the latest technology at home and abroad. This instrument is suitable for measuring the surface smoothness of paper and cardboard, and is an ideal testing equipment for departments such as papermaking, packaging, printing, commodity inspection, and scientific research.

This instrument uses high-performance microcomputers, high-precision sensors, German imported oil-free vacuum pumps, and professionally manufactured vacuum volume blocks and solenoid valves to achieve mercury free rapid measurement.

This instrument meets the following standards:

All performance parameters and technical indicators comply with standards such as ISO5627 "Determination of smoothness of paper and paperboard (Buick method)" and GB456 "Determination of smoothness of paper and paperboard (Baker method)"

Instrument features:

· Oil free vacuum pump: Adopting a German imported vacuum pump, the vacuum pump can work without refueling, and this instrument is oil-free and pollution-free when used

· Fast measurement: Small volume chambers can be used for measurement, with measurement time only one tenth of that of large volume chambers, greatly saving measurement time and achieving fast measurement

· Automatic discrimination and switching of volume chambers: The instrument has the function of automatically discriminating and switching between large and small volume chambers, and can measure and automatically distinguish situations such as "less than 15 seconds", "greater than 15 seconds, less than 300 seconds", "greater than 300 seconds", etc

· Automatic calculation function for two-sided difference: The instrument can measure the smoothness of the front and back sides of the paper as required, and can automatically calculate, display, and print the "two-sided difference" result

· Excellent sealing performance: Using foreign vacuum sealant and advanced sealing technology, the instrument's sealing performance meets the requirements of national standards

· Adopting a modular integrated printer, it is easy to install and has low malfunctions; Equipped with a thermal printer for high-speed silent printing.

· Chinese output display: Using a large LCD display module, it displays and prompts operation steps in Chinese, displays measurement and statistical results, and a friendly human-machine interface makes instrument operation simple and convenient, reflecting the humanized design concept
