The gauge is intended for use at technical car inspection centers, during routine police checks for compliance with new regulations and during the production of the vehicle windows and/or the maintenance thereof. To this effect the gauge complies with ISO 3558 and is suitable for a single person to operate - it's so simple, fast and easy to use.

And this is how it works: Attach the illuminant source to the clean outside windscreen or side window with the aid of the integrated suction cups and place the detector head on the inside of said window, carefully aligning the two parts. Integrated magnets in both the light source and the detector protect them from falling. The result (the indicated measurement is the transmittance in percentage, defined as the ratio of the absorbed by the glass to the light onto the glass) is displayed after a few seconds on the LCD creen once the measurement sequence has been initiated.
