Choose a colorimeter around the sample area, optical geometry and comparison method used in your work. Color-difference readings are most useful when the reference, sample preparation and measurement conditions are consistent.

Compare two different measurement setups

Model Measuring aperture Geometry What to consider
CR2 portable color reader 8 mm D/8, SCI Sample area, reference comparison and which functions need the app
LS175 colorimeter 20 mm 45/0 Coverage of a larger sample area and repeatable positioning on textured materials

A larger aperture samples a different area; it does not guarantee a correct reading on every curved surface. Check that the sample can cover the opening and be positioned according to the model's instructions.

Compare color results on the same basis

  • Use the optical geometry required by your procedure.
  • Specify the reference and color-difference formula before applying a pass/fail tolerance.
  • Compare repeatability only with its documented measurement conditions; it is not the same as absolute accuracy.
  • Check whether color libraries, averaging, storage and reports run on the instrument or require software.

A nearest color-library result helps narrow a selection. It does not prove that a paint formula or finished product will match under every viewing condition.

For an additional portable option, compare the CR3 portable colorimeter with the CR2 and review each model's documented functions.

For spectral reflectance data and spectrophotometer workflows, compare our color spectrophotometers.
