Product Description
Paper electric mercury-free smoothness tester
Paper electric mercury-free smoothness tester product uses:
The technical requirements and detection methods of the paper smoothness tester (mercury-free) comply with the international standards ISO5627 "Determination
of smoothness of paper and paperboard (Buick method)", QB/T1665 "Paper and paperboard smoothness tester" and other standards, it is an essential instrument for testing various high-smooth papers.
This smoothness meter is used for testing highly smooth paper and cardboard. It should not be used to test materials with a thickness above 0.5mm or paper or cardboard with high air permeability, because the amount of air passing through the sample can cause unrealistic results.
Product features
The instrument uses a high-precision vacuum sensor to measure the vacuum degree of the vacuum container, thus replacing the mercury manometer. Therefore, this instrument is a mercury-free smoothness meter. It uses imported vacuum mercury to extract vacuum from the vacuum container, which can achieve a very short time. It reaches the required vacuum degree and is controlled by a single-chip microcomputer; it also has powerful data processing functions: not only can the smoothness value of a single sample be measured and automatically stored, but also the experimental data of multiple samples in the same group can be counted.
The value, Z minimum value, average value, standard deviation and coefficient of variation of the same group of samples can be obtained. 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.
Main technical indicators：
