The RT 300 - 400 - 500 series of versatile, portable spectrophotometers is designed to give fast, precise and accurate colour measurement information on a range of products. They provide absolute and difference measurements in various colorimetric systems including CIE Xyz, CIE Yxy, CIE L*a*b*, Hunter LAB, CIE L*c*h*, CMC and CIE 94, Whiteness and Yellowness per ASTM E313-98, Metamerism Index and DIN 6172.

The RT 300 - 400 - 500 series stores up to 1024 standards with tolerances for easy pass/fail measurement. A red/green LED-illuminated indicator and the LCD display provide visual confirmation of results. A tone also sounds to indicate a fail result. To allow the operator to take quality-control readings in a time-efficient manner without having to create tolerances or store data, it is also possible to take a quick measurement and comparison of two colours.

The RT 300 and RT 500 include a special 'project Mode'. Each project maintains a group of standards from which the instrument selects the closest colour for comparison with measured samples. The projects mode helps to organise standards eg a project can represent a customer that has several standard colours for a particular product line.
