Introduction to the calibration cycle of gloss meter in material testing machine

Material testing machineThe gloss that operators often say refers to "mirror-oriented gloss", so gloss meter is a mirror-oriented gloss meter. The same testing equipment must be tested frequently, and the following is a detailed introduction to the testing time.

Glossmeters are metrological instruments and should be regularly verified according to their use to ensure the accuracy of the instrument. According to the provisions of the national metrology and verification regulations of JJG696-2002 "Mirror Gloss Meter and Gloss Plate". The calibration period of gloss meter and gloss plate generally does not exceed 1 year.

The light source G emits a beam of light through the lens L1 to reach the measured surface P. The measured surface P reflects the light to the lens L2. The lens L2 converges the light beam to the photocell located at the light column B. The photocell performs photoelectric conversion and sends the electrical signal to the processing circuit for processing, and then the instrument displays the measurement results.
