Hengaode instrument's new smoothness tester uses executive standards
Smoothness tester is a necessary instrument for testing various high-smooth papers, used for testing high-smooth paper and paperboard
Product Usage
The technical requirements and testing methods of the smoothness tester PN-BST (hereinafter referred to as the smoother) conform to the international standard ISO5627 "Determination of Smoothness of Paper and Cardboard (Buick Method)", QB / T1665 "Paper and Board Smoother" The requirements and regulations of the standard are necessary instruments for testing various high-smooth papers. This smoother is used for testing high-smooth paper and paperboard. It should not be used to test materials with a thickness of more than 0.5 mm or paper or paperboard with high air permeability, because the amount of air passing through the sample can cause unrealistic results.
Product Features
1. Three working states can be selected according to the smoothness of the sample;
2. Up to 20 measurement data can be memorized;
3. Analyze and process the measured data;
4. The lever and cam clamping mechanism make the operation very easy.
5. Modern design concept of electromechanical integration, compact structure, beautiful appearance and easy maintenance.
Executive Standard
GB / T 456 "Determination of Smoothness of Paper and Paperboard (Buick)"
ISO5627 "Determination of Smoothness of Paper and Paperboard (Buick Method)"
Features
The smoothness tester (also known as paper smoothness tester) uses a high-precision vacuum sensor to measure the vacuum of the vacuum container, thus replacing the mercury pressure gauge, so this instrument is a mercury-free smoothness meter; imported vacuum mercury is used Extract the vacuum from the vacuum container, can reach the required vacuum degree in a very short time, and is controlled by the single-chip microcomputer; it also has powerful data processing functions: not only can measure and automatically store the smoothness value of a single sample, but also can count The experimental data of multiple samples in the same group can count the maximum, minimum, average, standard deviation and coefficient of variation of the samples in the same group. These data are stored in the data memory and can be displayed through the digital tube; In addition, the instrument also has a printing function.
