X-Rite has optimized the 369 Diazo/Silver Film Densitometer specifically for diazo film measurement commonly used in printed circuit board and microfilm applications. Switch filter responses with the touch of a button to measure either UV (diazo) or ortho (silver) film. The 369 can directly measure 0.0 to 5.0 density with an accuracy of plus/minus .04D at 4.5D when using the 2mm aperture. A push button null automatically resets the 369 to 0.0D. The light intensity control feature on the 369 recognizes densities above 4.0 and automatically activates higher lamp intensity. The unit's on-board microprocessor delivers stable, accurate density measurements up to 5.0D. We've installed a special orange-colored light table on the 369 to minimize UV leakage. This built-in safelight will protect your diazo film from uncontrolled changes in density.
