Xrite x-rite 968 color spectrophotometer - nice
This is a used, X-Rite 968 Color Spectrophotometer.
The X-Rite 968 is a reflection
spectrophotometer. The 968 measures spectral reflectance from 400nm to 700 nm in 20nm intervals. It has a 0 illumination angle, a 45 viewing angle, and features a dual-beam, single light pulse compensation method to insure accuracy.
The 968 calculates colorimetric and spectrophotometric data. The 968 displays colorimetric data, and can output (to a printer or computer) colorimetric and spectral data. An optional software package,
SpectroStart , can collect, sort, view, and analayze L*a*b* and spectral data using an IBM (or 100% compatible) computer.
This instrument is in excellent condition and goes through calibration procedures OK. It has a new set of Rechargable Batteries installed

Manual and Reference Guide
The 968 measures spectral reflectance, absolute color or color difference, and absolute index or index difference for Whiteness and Yellowness.
XYZ or RGB & DXYZ or DRGB (CIE 1931 or RGB = X%Y%Z%) > Z% is one method used to measure paper brightness.
L*a*b* or Lab & DL*a*b* or Lab (CIE 1976 or HUNTER)
L*C*h & DL*C*H* (CIE 1976, ab, CMC, or uv)
Whiteness & Tint & DWhiteness & Tint (CIE & ASTM E313)
Yellowness & DYellowness (ASTM E313 & ASTM D1925)
The 968 has eight different CIE Illuminants for calculations under varying lighting conditions. In addition, you can select the CIE 1931 2 Observer or the CIE 1964 10 Observer.
Illuminant F2 (Cool White Fluorescent)
Illuminant F7 (Narrow-band White Fluorescent)
Illuminant F11 (TL84 / Wide-band Fluorescent)
Illuminant F12 (Ultralume 3000)
