ONLINE COLORIMETER
MODEL-3410

The instrument has diffuse geometry and CIELAB filters. Diffuse geometry provides a "color-only" reading reducing the effect of texture and gloss in the measurement. Spectral information between 400-780nm is used to calculate CIELAB (L*a*b*) color values and color difference (Delta E) values. Either D65 or C illuminate can be selected using a 2-degree observer. Brightness/Whiteness indices and CMC elliptical tolerances can be displayed. The software has storage with recall of standards and measurements. The software displays Delta L*, Delta a*, Delta b* and Delta E* trend plots. Pass-Fail values can be set for each trend line with warning for each value. The sensor is designed to read every ten seconds but able to read every second under certain conditions. Readings can be summed and displayed as an averaged value. A Xenon lamp (approx. 1 million readings) provides illumination for the reading. The sensor is positioned 1.0 to 6.0-inch above the measurement surface. Contamination on the measurement window is calibrated out of the reading. An optional hot mirror lens allows reading hot products up to 135-F. Calibration is manual and required every shift. Hitch management software is provided to correlate the online values to bench top sphere (SCI) instruments. The Colorimeter has a heavy-duty aluminum casing and is the companion instrument to the Dynagard-75 glossmeter.
