The Model 805A Surface Analysis System measures and analyzes the gloss level, distinctness of image (DOI), and orange peel and haze index of surfaces regardless of their shape, texture or color. It is also used to characterize surface texture. This high-resolution video imaging system readily supplies numerical values for surface finishes.

The quantitative values provided by the 805A eliminate all subjectivity in judging the surface characteristics. The system can measure up to 240,000 sample points per test. Specific areas of the test sample can also be isolated for measurement.

All gloss measurements are directly traceable to a gloss reference supplied with the system.

A distinctness of image (DOI) function provides a quantitative measurement of reflection clarity for products exhibiting very high gloss levels.

The orange peel function provides a means of precisely measuring the "orange peel" or "waviness" of product surfaces exhibiting orange-peel-like characteristics.

The 805A provides measurements used to calculate haze index.

The systems surface texture characterization function provides the capability to measure and monitor the consistency of textured surfaces.

Used to quantify surface characteristics and monitor consistency of product, the 805A in also invaluable for wear and weathering studies. It provides measurement data, image displays, histograms, data comparisons, internal calibration, and other in-depth information.

The 805A is menu-driven, and measurements can be obtained within seconds by simply pressing a button. The operator can also analyze the data, view histograms, and interact with historical data.

The 805A is comprised of a sample measurement chamber, personal computer and monitor. The system is self-monitoring and self-calibrating to ensure accuracy and ease of use.

TRICOR also offers other appearance instrumentation, including a hand-held surface analysis system, an appearance meter used to measure haze and micro pitting, and a video photometer which provides light reflectance and intensity measurements.
