Color of Transparent Liquids Compared with Liquid Standards for Gardner Color Scale

The color of transparent liquids is critical as a change can indicate contamination or impurities in the raw material or process variations caused by heating and oxidation.

Visual tests have been established by comparing the sample to a known standard. The standard that the sample falls closest to then becomes the value for the liquid.

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


  • Quick and easy color quality control of liquids
  • Rugged design for use in the laboratory and production
  • Attractive price – color evaluation of liquids becomes affordable to everybody

Color of Transparent Liquids Compared with Glass Standards for Gardner Color Scale

The Gardner Delta Color Comparator is an arrangement of two wheels in which nine precision-polished 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.


  • Quick and easy color control of liquids
  • Rugged design allows the color comparator to be used at any location

For simplicity, one dimensional scales for yellowness were established: Gardner, Hazen, Saybolt, Iodine.

BYK-Gardner offers a complete line of visual color comparators and objective instruments for liquid color measurement.

Color of Transparent Liquids Objectively Measured with Spectrophotometers

The LCM and LCS IV are reliable color instruments which replace conventional visual color evaluation with an objective measurement. They are ideal for routine production control of clear, transparent liquids and give reliable data on a consistent basis.


  • Automatic cuvette detection - avoids faulty data measurement
  • Work with 10 and 50 mm rectangle as well as 11 mm round cuvettes for optimum precision
  • Easy data transfer into existing networks through integrated Ethernet (LAN) interface
