Lower quality measurements using a glossmeter quantify the glossy appearance of a surface in gloss units.

The measurement results of a glossmeter are related to the amount of reflected light from a black glass standard with a defined refractive index.

Using a glossmeter, they measured gloss levels substantially higher than the value of 70 gloss units which is considered "high gloss".

A glossmeter (also gloss meter) is an instrument which is used to measure gloss of materials such as paint, plastics and paper.

The glossmeter provides a quantifiable way of measuring gloss intensity ensuring consistency of measurement by defining the precise illumination and viewing conditions.

Numerous international technical standards define the method of use and specifications of different types of glossmeter used on different types of materials.

The measurement scale, Gloss Units (GU), of a glossmeter is a scaling based on a highly polished reference black glass standard with a defined refractive index having a specular reflectance of 100GU at the specified angle.
