How to Choose the Right Gloss Meter and Glossiness Measurement
Every kind of object will have the gloss, some gloss is high and some gloss is low. The object surface gloss directly affects the aesthetics of the object, so we generally use a gloss meter to measure the gloss of the object surface.
1. What is the gloss of an object?
The gloss of an object's surface is mainly determined by the surface's ability to reflect light specularly. In simple terms, it is a kind of light reflection phenomenon (that is, the incident angle and the reflection angle of the light are equal). Gloss value is a physical evaluation of an object's ability to reflect light on the material surface. Gloss values are divided into several categories. The gloss values we generally refer to are "mirror gloss." Therefore, the gloss meter is also called a specular gloss meter.
2. How to choose the right gloss meter?
(1) Distinction of gloss
The gloss unit is generally expressed as "GU". Generally, the gloss value is above 70GU. We divide it into high gloss. The semi-gloss gloss value is divided into 30GU-70GU, and the eggshell gloss is generally 6GU-30GU. The gloss of flat light is generally 2GU-6GU. There is nearly no gloss when it is below 2GU.
(2) What are the gloss meters?
The gloss meters on the market are mainly gloss meters with angles of 20 degrees, 45 degrees, 60 degrees and 85 degrees. These gloss meters are mainly distinguished by the incident angle of the light source. Common gloss meters include 20-degree, 60-degree and 85-degree angles. The gloss meter is distinguished from the range by 0-1000GU, 0-2000GU and 0-200GU.
(3) Choose the right gloss meter
We have learned the relevant knowledge about gloss, so how to choose a appropriate gloss meter? Simply put, it is a gloss meter with a small angle for high gloss products. For low-gloss items, choose a large-angle gloss meter. In detail, if the gloss value is greater than 70GU, we will generally choose a 20-degree gloss meter. For gloss values less than 30GU, a gloss meter with an angle of 85 degrees is generally used. The 60-degree gloss meter is a universal gloss meter. 45 degree gloss meter is generally used to measure the gloss of paper.
3. Use the gloss meter to measure the gloss of the paper
Linshang Technology has invented two gloss meters, LS191 and LS192, both of which are 60-degree gloss meters. The test range of the gloss meter LS191 is 0-200GU, which is suitable for measuring the gloss value of low gloss materials. Such as paint, paper, leather, ceramics, stone, etc.
The test range of LS192 is 0-1000GU. This gloss meter has a wider measurement range and is also suitable for measuring the gloss value of high-gloss materials. These two instruments are small, exquisite and easy to carry. The measurement accuracy is in line with the standards of national first-class working machines. It is your best choice for gloss value measurement.
