LCNDT DT-300 Desktop Digital Densitometer

LCNDT DT-300 Desktop Digital Densitometer

Highly Accurate Densitometer with 5 brightness settings and High Luminance Spot LED that can measure up to 5.0D film

Effortless Accuracy

Replaces the X-Rite 301 Densitometer

The DT-300 is a robust and easy to use tabletop densitometer for measuring black and white transmission x-ray film. This unit provides highly accurate and repeatable measurements of film with densities up to 5.0D, and its high luminance spot light provides more subtlety than can be seen by the naked eye. Designed to be used in darkrooms, laboratories and offices, the DT-300 is truly a powerful unit that provides easy measurement of film anywhere you need it to. 


  • LED Lit Table with 5 brightness settings and 2 light sections
  • High Spot Luminance which simplifies locating image areas to measure
  • Program Mode for custom calibration
  • Will remain properly aligned even when picked up by the arm
  • Calibrated to AGFA film strips
  • Measuring Range: 0-5.0D, High Accuracy ±0.02D
