Specific materials require specific measuring angles: Ceramic materials, plastic films and solid plastics, paper and paperboard either measure specular gloss at the standard geometries 20°, 60°, 85° or at industry specific geometries 45° or 75°.
Plastic films and solid plastics, both opaque and transparent, are often measured at 45° angle for intermediate and low gloss levels. For films that transmit light, a matte black backing such as "Black scrub panel" part #5015 must be placed behind the sample. Erroneous measurements will occur without a suitable backing. Standard test methods ask for readings on at least three portions of each specimen to get an indication of gloss uniformity. The statistic mode of the micro-gloss will show the average and range or standard deviation as a measure of sample uniformity. Ceramics, porcelain enamels and other finishes use the 45° geometry and often provide a comparison of their resistance to
acid, alkali, or other environmental factors by measurement of gloss loss.

NEW: smart-chart software - instant QC reports with trend graph and Pass/Fail limits

- Brilliant color display: easy to read - easy to use. The scroll wheel operation and new color display with an easy-to-navigate menu make gloss measurement easier than ever before.
- Accurate readings require reliable calibration. The gloss meter and calibration holder make a perfect couple - the calibration standard is always protected in the holder of the micro-gloss. The intelligent auto diagnosis of the gloss meter is a unique feature which guarantees long-term calibration stability and tells you when to calibrate. It even checks whether the standard is clean. Operator friendly. Safe.
- With the micro-gloss gloss meter you can measure any material - paints, plastics or brightened metals. Its expanded range measures from very matte to mirror like reflection of up to 2000 gloss units, automatically and without additional calibration. Always reliable results - according to international standards Every measurement series can be saved in the glossmeter under its own name. 

Different tasks require different tools. The easy to turn scroll wheel of the glossmeter quickly shows you all needed functions - even without a PC:
The BASIC MODE is your tool to quickly check the gloss of a few samples.
The STATISTIC MODE not only shows the average, but all statistical data needed to judge whether the measured difference is significant or how uniform the surface gloss is on your sample. You define what you want to see: mean, standard deviation, range, min/max, ...
The DIFFERENCE MODE allows you to define a reference with Pass/Fail limits and will compare all of the following measurements to the selected reference. The Pass/ Fail indication is colorfully shown on the high resolution display - ideal for production control. 
The CONTINUOUS MODE is the most efficient way to quickly check the uniformity of a large sample surface. You define the measurement interval and are now ready to continuously measure the gloss by sliding the micro-gloss over the surface. When finished, the average with min - max range are displayed.
