How to Choose a Gloss Meter

Nov 11,2020
Gloss meter, also known as gloss machine, gloss measuring instrument, gloss determining instrument, gloss testing instrument, gloss detecting instrument, and gloss tester. The gloss meter is widely used as supporting special measuring instruments for chemical raw materials, paint manufacturing, automobile industry, electronics industry, electrical industry, etc.. The high-precision gloss meter can be divided into three types according to the angle: high gloss meter, medium gloss meter and low gloss meter.
The gloss meter is an instrument used to measure the gloss of various materials, such as ceramics, paints, inks, plastics, marble, aluminum, hardware, granite, coatings and others. Many users don't know how to select when buying a gloss meter. The following will introduce what should be paid attention to when making a purchase.
I. Standard plate
The measurement of the gloss meter must have the data of the gloss standard plate as the reference standard. If the standard plate is not accurate, the instrument must be inaccurate. Moreover, the gloss of the standard plate is very easy to be stained, so the standard plate of the instrument must be well protected. Generally, a special base is used. The standard plate is embedded in the base to avoid external pollution and scratches.
II. Standard board contamination self-diagnosis function
The gloss meter must have a self-diagnosis function for standard plate contamination, that is, if the standard plate is dirty, the instrument can recognize and prompt the user to clean the standard plate. Otherwise, the calibration is wrong, and all measurement data will be inaccurate.
III. Temperature compensation function
The gloss meter has a temperature compensation function. The principle of gloss meter is to use a light source and a receiver to measure the reflected light flux on the surface of the material. If after the instrument is adjusted, there is a change in the ambient temperature, resulting in a change in the luminous efficiency of the light source, then the error of the change in the luminous efficiency of the light source will be directly reflected in the measurement data. If there is a temperature compensation function, then the change in luminous efficiency caused by temperature changes can be compensated to ensure that the luminous efficiency of the light source remains unchanged.
IV. Stability
When buying a gloss meter, its stability, consistency and accuracy must be considered. This is a very important reference factor and has a great impact on its overall performance.
