The RT series offers a choice of compact, reflectance colorimeters, giving spectral data<br />

<strong>for</strong> quality control of surface colour. The Lovibond RT100 consists of a hand-held<br />

spectrophotometer unit with an integrated measuring head (45 o / 0 o measuring<br />

geometry) <strong>for</strong> precision colour measurement and control of regular surfaces. The<br />

Lovibond RT200 consists of a similar spectrophotometer unit but with a flexible,<br />

fibre-optic measuring head (0 o / 0 o measuring geometry) <strong>for</strong> colour measurement of<br />

small areas, challenging shapes or relatively inaccessible places.<br />

The RT100 and RT200 instruments both combine advanced microspectrometer<br />

technology with the computing power of a PC. The spectrophotometer units link to a<br />

standard PC computer with software installed <strong>for</strong> instrument operation and <strong>for</strong><br />

presentation, analysis and logging of reflectance data. Results can be expressed in a<br />

choice of colour values and colour difference measurements.<br />
