Electronic smoothness tester without mercury

 

 

The instrument is used for determining the surface smoothness of paper and paper board and the structural parameters and technical characteristics of the instrument are in conformity with standard requirements of QB/T1665<Paper and Paper Board Smoothness Tester> and GB465<Paper and Paper Board Smoothness Determination Method(Beaker) > .

Structural characteristics:

1. Box structure is adopted for the instrument. It is compact and artistic:

2.  Air-wedge technology is taken as the principle of the testing method, electronic inspection and control , the test result is digitally displayed, (                         )

3..The vacuum degree measuring system with high accuracy sensor as the transition element:

 4.The system adopts the digital circuit technology with chip microcomputer as the central processing unit, and specific software is offered for control, measurement, data collection and processing to the complete appliance.

 5.The display window shows the test result, Beka smoothness value is directly shown whatever large volume or small volume is used.

6.The printer prints test report, and the content of printed report is complete, including test date, maximum value, minimum value, average value, standard deviation, coefficient of variation, etc, and it is very convenient to use.
