Liquid Color Standards
Liquid Color Standards The Gardner Liquid Color Standard Comparator provides the entire Gardner Color Scale, against which a liquid sample can be visually compared.

The sealed tubes are filled with Cobalt Chloride Platinate solutions of varying concentrations, which correspond to known Gardner Scale yellowness value numbers 1 – 18. The solutions are standardized at 25°C (77°F), but visual evaluations made between 20°C (68°F) and 30°C (86°F) are substantially correct. Two models are available: with or without illumination.
