Gloss Meters

Quick, easy, accurate gloss measurement

Our digital gloss meters are quick and easy to use to test gloss levels, with just two buttons – Power and Measure. Simply place the meter against the surface to be checked and press the Measure button. The gloss level (in the range of 0-200 GU) is immediately displayed on the meter’s LCD screen. The user does not need to go through complicated settings or menus prior to use, saving time and improving efficiency.

The meters automatically display gloss level readings in Gloss Units (GU), the unit specified in international standards for gloss measurement. The display resolution is 0.1GU.

The meters can be calibrated with the included calibration piece. User replaceable batteries eliminate the risk of long-term internal battery deterioration and prevent costly and inconvenient downtime due to lack of charge.

GM1 Gloss Meter – Single Angle

The GM1 gloss meter takes readings at a single reflecting angle of 60°. This angle is considered flexible for use across all gloss levels.

For enhanced differentiation at high and low gloss levels, alternate measuring angles can also be considered (see our GM2 model). Additionally, if comparing gloss level measurements to a specification, they must be taken at the same angle.

GM2 Gloss Meter – Triple Angle

The GM2 gloss meter simultaneously takes gloss readings at three reflecting angles. This multi-angle measuring capability means it is suitable for measuring the widest variety of surfaces and gloss levels. This functionality eliminates the need to own multiple meters of different specifications and its capability to take simultaneous readings at each angle speeds the measurement process.

Its 20° angle provides enhanced differentiation on very high gloss surfaces such as polished metals and its 85° angle provides enhanced differentiation on very low gloss surfaces such as matt paints. If a gloss reading is over 70GU at 60° then the reading at 20° is often selected. If a gloss reading is below 10GU at 60° then the reading at 85° is often selected.

As well as assessing gloss, haze can also be calculated by subtracting the gloss reading at 20° from the gloss reading at 60° to achieve a haze index in accordance with the ASTM D4039 test method.

Work on many surfaces

The GM1 and GM2 gloss meters can be used in testing the gloss levels of a variety of surfaces and coatings. This includes but is not limited to: paint, powder coating, plastic, carbon fibre, fibreglass, ceramics, varnish, vinyl, ink, paper, cardboard, metal, leather, and wood. The user does not need to adjust any settings between different surfaces.
