Despite its simple operation, the CM-5 is equipped with a full range of advanced functions for standalone operation and a large color LCD that can show data not just numerically but also on spectral graphs and color plots without the need for a separate computer. Measurements of both reflectance and transmittance are possible, and judgment of PASS/FAIL based on user-set tolerances can be performed.
The CM-5 has internal calibration curves for several of the standard color indices used in the chemical and pharmaceutical fields: Gardner, Hazen/APHA, Iodine Color Number, European Pharmacopoeia, and US Pharmacopeia, so measurements based on these indices can be taken easily by anyone.
