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.

Sample Adapters

A selection of fixtures and accessories for standardised measurement of product samples:

Benchtop Stand

The Benchtop Stand is designed to hold the instrument and sample steady, ensuring accurate and repeatable measurements. It holds the instrument in an upright position for vertical sample measurements or in an upside-down position for horizontal measurements.

‘Liquid’ Cell Holder

Suitable for liquids, powders and semi solids. It features a black chamber with a white ceramic backing that encloses the sample filled cell. When using the Liquid Cell Holder we recommend that the instrument is held in a vertical position using the Benchtop Stand.

Powder Cell Holder

Suitable for liquids, powders and semi solids. The Powder Cell Holder holds a circular cell, which is enclosed in a black chamber to prevent ambient light from affecting the measurement. When using the Powder Cell Holder we recommend that the instrument is held in a upside-down position using the Benchtop Stand.

Pellet Holder

Suitable for samples in pellet form.

V-block Sample Holder

The V-block sample holder is designed to hold odd-shaped parts for measurement such as bottle preforms
