Measuring Functions and Indices
The Lovibond® RT300 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.

Flexible Measurement Modes
The RT300 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.

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.

Opacity, Colour Strength and Shade Sorting
The RT300 can measure opacity as well as three colour strength options: chromatic, apparent and tristimulus calculations. They also perform 555 shade sorting. These are important considerations in the colour quality control of manufactured products involving plastic, painted or textile materials.

User-Friendly Ergonomics
In addition to on-board programmes to assist the operator in the data collection process, the instruments themselves are highly user-friendly. They are compact and lightweight. A wrist strap and tactile side grips make them easy to hold. Read-outs are large and easy to see. A rechargeable battery pack allows extended operation of the instrument.
