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 />
