Both reflectance and transmittance measurements are possible using this one unit, with availability to measure various types of solid, liquid, powder, pellet and ;film sample in the range of 380nm to 780nm at 10nm output wavelength interval. alt



1. Measurement is possible in the range of 380nm to 780nm at 10nm output wavelength interval.
2. Standard light or target light can be selected as a light source for the measurement of metamerism.
3. C / 2º or D65 / 2º can be selected for Munsell color system.
4. A foot switch comes equipped with this instrument, by whitch you can make measurements even by both hands free. It will be convenient in case you measure a sample by holding it by your both hands.
5. Measurements of Harzen color numbers (APHA) and Gardner color system are available in option.
6. Color data analysis will be available when you use an optional color management software.

Measurement accuracy
  • ΔE* : Standard deviation within 0.02
  • Spectral reflectance : Standard deviation within 0.20 or less

where 30 minutes later after turning on the power, 30 times of measurements are made at 10 seconds interval against a standard white plate, and repeatability is checked.

  • Color management software (Color Mate 5)
  • Optical fiber, etc.
