Overview
Paper and Cardboard thickness tester is a special instrument for paper and Cardboard Film thickness measurement. Its main technical indicators and performance parameters comply with the relevant provisions of GB4513 "Paper and Cardboard Film thickness determination method", which can be widely used in paper, Cardboard and Miscellaneous film thickness measurement.
Features
1. Measurement range is wide, up to 0~ 20mm.
The contact pressure is accurate at 20 +/- 0.5 kpa.
3. Contact area standard, 10 +/- 0.2cm.
4. High parallelism of measurement surface, ≤ 0.035mm.
5. Indication Error is small, +/- 0.03mm.
6. High resolution, up to 0.001mm.
Principle
The instrument applies a standard contact pressure (20 +/- 0.5kpa) to the measurement head of the standard contact area (10 +/- 0.2cm ²) to make contact with the sample, so as to accurately measure the film thickness of paper, Cardboard and other sheet materials.
Applications
Paper, Cardboard, Miscellaneous Sheet Material
Standards
QB/T 1035 "Paper and Cardboard thickness tester", QB/T 451.3 "Paper and Cardboard Film thickness determination method", QB/T 1055 "Paper and Cardboard thickness tester", ISO 438 "Paper-laminated Film thickness and tightness determination", ISO 534 "Paper and Cardboard - Determination of single layer Film thickness and Cardboard tightness calculation method"
Steps
1. Ensure that the instrument is in a suitable working environment (temperature (20 +/- 10) ℃, humidity < 85%).
2. Place the sample to be tested flat on the measurement table.
3. Operate the instrument so that the measurement head is in contact with the sample under standard pressure.
4. Read and record Film thickness indication on display screen.
Notice
• Make sure the instrument is calibrated before use.
• When measuring, ensure that the surface of the sample is flat and free of wrinkles.
• Do not use the instrument in an environment beyond the specified Humidity range.
• Keep the measurement surface clean to ensure Measurement accuracy.
