6.Stable test data

There is a white LED light source in the gloss meter. The luminous efficiency of the light source will change with the change of temperature, so the ordinary gloss meter needs to be calibrated before the test. The Linshang gloss meter has temperature compensation function. When the temperature difference changes very much, it does not need to be calibrated every time it is turned on. And this gloss checker can ensure the stability of the test data. Especially in northern China, the temperature difference between morning and evening is very prominent.

7.Small size

The LS191 gloss tester has small size. It is designed with all-aluminum material. It is very convenient to carry out and not afraid of various crash that may affect the appearance.

8.Ultra-low power consumption

This gloss tester is powered by a built-in lithium battery, which is energy-saving and environmentally friendly. It has ultra-low power consumption. The continuous uninterrupted test time can reach more than 50 hours.

  2. 2. What is repeatability and reproducibility?

    Repeatability is the difference between multiple measurements of the same sample under the same conditions, the same people, the same gloss meter and the same environment.

    Reproducibility refers to the difference of measuring the same sample under different conditions, such as the same people using different gloss meters, or different people using the same gloss meter.

  3. 3. What is the zero value error?

    When testing a material with 0 GU, the difference between the measured value and 0.
