The Starr Instruments GMX-03 allows users to measure and analyze the specular reflection (gloss level) at 3 different incidence angles (20/60/85°) to suit a wider range of materials, including extremely matte and glossy surfaces. 

Operation is Simple. With the click of the button, 3 light beams are transmitted across all the angles onto the test surface, which is reflected into the receiver sensor.  The corresponding Gloss Unit (GU) values are displayed on the screen instantaneously.

In additon to this, documented results when connected to a computer can be exported through the software provided. These results are incredibily accurate with a repeatability of ±0.2 GU, allowing for consistent and reliable results across any range of measurement.  

ASTM D523 states that if your gloss reading at 60 degrees is more than 70 GU, then it is considered to be high gloss and should be remeasured at 20 degrees angle.  Alternatively if your gloss reading is less than 10 GU, it is considered to be matte and should be remeasured at 85 degrees. The GMX-03 provides all 3 of these readings simultaneously. This helps to eliminate any human error which could occur when changing between angles.
