Gloss Meter IG-331
Gloss meter with measuring geometry of 20° and 60° and external detector head at a spiral cable

Digital gloss meter with high accuracy. Colour and brilliance are the most important factors for determination of surface- characteristics. This gloss meter stands out compared to its forerunner model due to an automatic zero balance. It is ideal for on-site measurement and can be applied on all plain surfaces (e.g. stone-, wooden, laminate, rubber floor etc.), whether they are treated or not. The visual evaluation of colour and brilliance is highly dependent on individual cognition of observer and exterior influences (surrounding colour and brightness). Furthermore the possibilities to determine a brilliance impression in words or to document them are very limited. Only the application of gloss meters that work on international standardized systems can help. Thus an objective description of brilliant products or surfaces is secured. If you have further questions concerning the gloss meter, please take a look at the following technical data or call our hotline: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. Our technicians and engineers will be pleased to inform you concerning the gloss meter ig 331 or any other product in terms of regulation and control or scales and balances of PCE Instruments.

Operation principle

Brilliance is measured through the reflection of light that hits the surface. The determination can be achieved due to the percentage of reflected light from the point of impact to a reflecting plate integrated in the gloss meter. According to standardization the limiting value on a glass surface with a refraction index of 1.567 should show a measured base value of 100 at the display of the gloss meter. As a reference base for re-calibration a black glass plate with a limiting value of 90 at a 60° angle and 84 at a 20° angle is used.

- 2 different angles / high accuracy
- 2 optic systems for different measuring
  angles of 60° and 20°

Thus a higher accuracy and efficiency during brilliance measuring can be achieved at a wide range of operation. 60° is for conventional ranges of high and low brilliance. 20° is used for high brilliance measurement.

The gloss meter is also being used as a correlation device for sleekness measurement. A high brilliance means mostly a high sleekness, which can provide an informative help for the evaluation of flooring. For sleekness measuring a rawness meter can also be helpful.

Application:
- Product evaluation 
- Building inspection
- Flooring/ floor care
- Lacquered surfaces (e.g. at automobile)
- Polished surfaces/ Polish
- Quality inspection (e.g. synthetic surfaces or
  paper surfaces during receiving inspection)
- In corporate laboratories
- During field work (e.g. during product
  reclamations of customers)
- In areas of research and development

Exemplary measuring of a lacquered surface

Here you can see the gloss meter during measurement of stone flooring. For measurement on stone it is to consider that being a natural substance that has dissimilar deep embedding it reflects light at various intensities. Thus you will not be able to replicate the measuring value. Therefore it is mandatory to select multiple measuring sectors. It is to say that in general alternations of max. 15 brilliance units are not detectable with the naked eye. Only values above 15 are distinguishable.

Note regarding accuracy:
By using two measuring systems the values determined via gloss meter become more accurate. With a measuring angle of 60° objects with lower or higher values are detectable, whereas a measuring angle of 20° operates only at high brilliance, i.e. when during a measurement with 60° a peak value of more than 70 is achieved. Therefore please review the adjoining sketch.
