Choosing the Right Digital Gloss Meter for Your Application

Choosing the Right Digital Gloss Meter for Your Application
November 02, 2023

Many instruments and tools are used in industrial applications to determine the quality of the products. One such instrument is a digital gloss meter. It is used for measuring the reflection and sparkle of the surfaces.

It projects light emissions at a constant level. When the meter is pointed at the surface, it calculates the reflected light at the reverse angle.

To maintain accuracy and perfection, it is important to do specific settings, each according to the surface being measured.

One can buy a quality product from any of the digital gloss meter manufacturers in india.

If you want to measure the reflection of non-metals, such as plastics and coatings, the reflected light intervals are at a further point of illumination when the light falls on the surface and is either fed inside or dissipated by the shading of the surface.

In applications where the measurements are performed above ~120GU at any angle, it is better to have an optional extra mirror calibration tile so that accuracy can be maintained.

In some surfaces, one angle may be above the threshold, and another is below. In such a situation, automatic range selection might fail, and the instrument gets into a loop. So, the correct range needs to be chosen manually in the measurement menu.

Which range is ideal for your purpose? You need to perform a measurement on the test surface. If you get results of more than ~120GU, then you can use the mirror range.

Low Gloss of 85°

It denotes the enhanced precision of low gloss. Here, the measurement of the surface is done by using an 80-degree angle. It can measure variations in texture and the angle has a wider spot of measurement.

Medium Gloss of 60°

Here, the standard measurement angle is 60°. One can get more robust ratios for an intense gloss with reciprocal angles of 85° or 20°.

High Gloss of 20°

It is an acute measuring angle. This gives a better resolution to surfaces with high gloss. It is possible to measure surfaces that weigh 70 GU or more at a normal angle of 60°.

The angle of 20° is vulnerable to haze effects, which may affect the surface appearance. The contrasting shine of the two samples is seen more clearly with this angle.

Glossmeter of 45°

It is mostly used in industries making films and ceramics.

Glossmeter of 75°

This is primarily used in the vinyl and paper processing industries.
