Before checking of color, glass cell (1 inch and 5 A1/4 inch) was washed, cleaned and dried followed by the measuring of color using Lovibond Tintometer
The PFXi-880, -950 and -990 spectrophotometers, from the Lovibond Tintometer
Group, are electronically sensitive instruments that register accurate readings efficiently and quickly on optically clear product samples.
Instrumental color measuring methods such as a Lovibond Tintometer
or Hunter Tristumulus Colorimeter are useful in eliminating the many variables which frequently occur during a visual assessment of the color sample.
Colour was checked in Lovibond Tintometer
(Tintometer Corporation Salisbury England).
The technical concept from Lovibond Tintometer
saves time, cost and the environment.
