20º / 60º / 75º Statistical Triple Angle Gloss Meter

  • Measures 20º, 60º and 75º Geometries
  • Simultaneous read of all 3 angles
  • Full statistical analysis
  • Suitable for measuring paper

The Novo-Gloss 20/60/75ºS gloss meter is a fully featured instrument measuring the gloss of surfaces.

The 60º angle is the reference angle and can be used to measure any surface from matt to mirror finish. To complement this the instrument also has 20º angle for improved measurement on high-gloss surfaces and 75º which gives improved resolution on matt surfaces.

With built in statistical analysis and ‘move and read’ for the checking of large surface areas, the instrument has all the features you will ever need for fast accurate gloss measurement.

The 60º can be used for measuring printed substrates, the 20º gives improved resolution on high-gloss coating and foil boards. The 75º is the standard measurement angle for gloss in the paper industry.

  • Full Statistical Analysis
  • Constant Read Feature
  • Auto-ranging, Measures Matt to Mirror Finish
  • Rechargeable Power supply
  • Extended two year warranty
  • Accurate and reliable
  • Calibrate to any standard
  • User Serviceable light source

Why Measure Gloss?

Gloss is an aspect of the visual perception of objects that is as important as colour when considering the psychological impact of products on a consumer.

It has been defined as 'The attribute of surfaces that causes them to have shiny or lustrous, metallic appearance.'

Manufacturers design their products to have maximum appeal: highly reflective car body panels, gloss magazine covers or satin black designer furniture.


It is important therefore that gloss levels are achieved consistently on every product or across different batches of products.

How is Gloss Measured?

Gloss is measured by shining a known amount of light at a surface and quantifying the reflectance. The angle of the light and the method by which the reflectance is measured are determined by surface and also aspect of the surface appearance to be measured.

Which Angle Should I Use For My Application?

ASTM D523 (the most commonly used standards) describe three measurement angles to measure gloss across all surfaces.

Gloss is measured in gloss units (GU) and is traceable to reference standards held at NIST.

Universal Measurement Angle: 60°

All gloss levels can be measured using the standard measurement angle of 60°. This is used as the reference angle with the complimentary angles of 85° and 20° often used for low and high gloss levels respectively.

Low Gloss: 75°

For improved resolution of low gloss a grazing angle of 75° is used to measure the surface. This angle is recommended for surfaces which measure less than 10GU when measured at 60º.

This angle also has a larger measurement spot which will average out differences in the gloss of textured or slightly uneven surfaces.

High Gloss: 20°

The acute measurement angle of 20° gives improved resolution for high gloss surfaces. Surfaces that measure 70GU and above at the standard angle of 60° are often measured with this geometry.

The 20° angle is more sensitive to haze effects that affect the appearance of a surface.
