Gardner-Delta Color Comparator

Gardner-Delta Color Comparator


The Gardner-Delta Color Comparator permits easy, effective visual evaluation of varnishes, drying oils, fatty acids and other oil derivatives, lacquers, and similar transparent colored liquids.

It consists of two basic parts: a comparator of 18 precision glass color standards and a special illuminator which provides a color-corrected light source.





  • The Gardner Delta Color Comparator uses precision-polished optical-glass filters as reference standards.
  • Comparison of sample tube against 18 precision-polished optical glass filters on two filter wheels
  • Rugged design allows the color comparator to be used at any location
  • Quick and easy color control of liquids
  • Optional illuminator allows back-light color to improve viewing conditions

Instructions for Use

The comparator is an arrangement of two wheels in which nine color filters are imbedded in each wheel. The glass filters range in color from water white through deep amber. A tube of the sample liquid is placed between the two filter wheels. The user then rotates the color wheels until the filter glass closest in color to the liquid is in place. That filter notation then becomes the color description for the liquid.
