Paperboard Smoothness Tester / Meter / Testing Machine / Equipment / Instrument / Apparatus / Device
This instrument is designed according to the smoothness measurement method (Buick method) of GB/T456-1989 paper and paperboard,is used for measuring the smoothness of paper and paperboard.However, it is not suitable for measuring paper with a thickness of 0.5 mm or more or with high air permeability.
Description
The instrument uses a high-precision vacuum sensor to measure the degree of vacuum in the vacuum vessel and replaces the mercury pressure gauge. Therefore, the instrument is a mercury-free smoothness meter.The instrument adopts a vacuum pump imported from Germany to vacuum the vacuum container and can reach the required vacuum degree in a very short time and is controlled by the single chip microcomputer.
The instrument uses the one-chip computer also has the powerful data processing function:Not only the smoothness value of a single sample can be measured and automatically stored, but also the experimental data of multiple samples in the same group can be counted, and the maximum value, minimum value, average value, standard deviation and coefficient of variation of the same group of samples can be counted. These data are stored in the data memory and can be displayed on the screen.
