Surface gloss meter is an instrument used to measure the surface gloss of materials, which can be used to measure the surface gloss of paper, plastic, metal, ceramics and other materials. This article will introduce the selection points and precautions of the surface gloss meter in detail.
select points
Measuring range: The measuring range of the surface gloss meter is usually 0-2000 GU, and an instrument with a suitable measuring range should be selected according to actual needs.
Measuring geometry: The measuring geometry of the surface gloss meter has different specifications, such as 20°, 45°, 60°, etc. The instrument suitable for the measurement geometry should be selected according to the surface characteristics of the measured object.
Stability: The stability of the instrument is an important factor to ensure accurate and reliable measurement results. An instrument with high stability should be selected to avoid errors caused by instrument instability.
Data processing: Some surface gloss meters are equipped with data processing functions, such as storage, statistics, analysis, etc., and an instrument with corresponding functions should be selected according to actual needs.
Precautions
Calibration: The surface gloss meter should be calibrated before use to ensure the accuracy of the measurement results.
Cleaning: The optical system of the instrument is very sensitive to dust and dirt, the optical part of the instrument should be cleaned regularly to ensure the accuracy of the measurement results.
Environmental factors: Gloss measurement is very sensitive to the interference of ambient light. The instrument should be placed in an environment that avoids direct sunlight and has sufficient and stable light.
Technical requirements: The operation of the surface gloss meter is relatively complicated, and it is necessary to be familiar with the relevant measurement principles and operating techniques to ensure the accuracy of the measurement results.
