DTP 644 High precision transmission densitometer with built-in light source and a throat more than 20 cm. long for measurements on large films. The lighted area around the reading aperture makes film positioning easier. Interchangeable measuring apertures (2.5 mm. and 1 mm.) complete DTP 642 characteristics. Functions: transmission density up to 6.00D and very accurate dot area measurements (0 - 100%).
=======================================
DTP 644 UV Ultra Violet response densitometer to be used for measurements on new silver-free films. Its throat more than 20 cm. long allows measurements on large films. The lighted area around the reading aperture makes film positioning easier. Interchangeable measuring apertures: 2.5 mm. and 1 mm. Functions: transmission density up to 4.00D and very accurate dot area measurements (0 - 100%). |
