Specifications of DTP41

Fast, Affordable, Versatile, Accurate Measurement Solution

DTP41 is a strip reading spectrometer that measures color with spectral technology. Whether your need is for color calibration, color process control or color management, the DTP41 autoscan spectrophotometer gives precise color measurements.

The DTP41 offers a UV model to help deal with fluorescent paper brighteners commonly found in proofing papers. Reducing the fluorescent effect from the brighteners, the UV model will assure accurate color measurement on these media.The transmission model, DTP41T, offers dual reflection and transmission capability which is an extremely versatile tool for a variety of applications including photo transparencies, research and testing.
