The micro-gloss 75° is a specialized glossmeter for paper, paperboard and structured plastic e.g. vinyl siding.
Especially coated paper, but also a variety of uncoated papers, request gloss control. The 75° geometry is suitable for most ink films on paper and paperboard. Color differences have a negligible influence on measured gloss. For example, a white surface will measure less than one gloss unit higher than an otherwise identical black surface. Very high gloss papers (lacquered, highly varnished or waxed) should use a 20° measurement geometry. As defined in the TAPPI standard for batch QC at least ten test specimens free from folds or wrinkles or other imperfections are to be checked. The smartlab Gloss software is ideal to document and communicate the measurement results. Its project management can be used to record the quality of one material over time and send the data either by PDF or Excel to all involved parties.
Another typical material to be tested for specular gloss using the 75° geometry is vinyl siding made principally from rigid PVC and is used to clad exterior walls of buildings. In order to evaluate the uniformity over large areas, the "Continuous mode" of the micro-gloss will display the gloss values in a predefined measurement interval while moving the instrument over the surface.
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.
