Overview
YT-CA725 paper dust degree tester is a professional equipment manufactured according to the standard GB/T1451-1989 "Determination of Paper and Cardboard Dust Degree" for measuring paper surface dust degree. The instrument has reasonable structure and convenient operation. It is widely used in Universities & colleges, R & D institutions, Quality control departments, and paper printing Encasement production departments to test paper materials.
Features
1. Adopt 20W fluorescent light source, illumination angle 60 °
2. Table size 270 * 270mm, swirling/spinning 360 °
3. Standard dust map area range 0.05~ 5.0mm ²
4. Wide voltage range AC 200~ 240V, 50~ 60Hz
5. Effective working area 0.0625 m2
6. Dimension 428 * 350 * 250mm, weight 12.5Kg
Principle
The instrument irradiates the surface of the paper sample at a 60 ° irradiation angle through a 20W fluorescent light source to observe and measure the dust degree on the paper surface on the workbench. The workbench can be 360 ° swirl/spin to observe the sample from different angles, and the dust degree can be determined by comparing the area range of the standard dust map.
Applications
Universities & colleges, R & D institutions, Quality control departments, paper printing Encasement production departments
Steps
1. Prepare more than 4 250mm x 250mm samples
2. Place the specimen on the workbench
3. Turn on Illuminant Irradiation Specimen Surface
4. swirl/spin table viewed from different angles
5. Compare the standard dust map area to determine the dust degree
Notice
• This instrument cannot be used in flammable and explosive environments
• The laboratory should maintain a temperature of 23 +/- 1 ° C and a relative humidity of 50 +/- 5% RH
• There should be no vibration in the room, no electromagnetic interference, and slight air flow
• There should be no vibration source around the installation environment of the instrument
