The RT series offers a choice of compact, reflectance colorimeters, giving spectral data
for quality control of surface colour. The Lovibond RT100 consists of a hand-held
spectrophotometer unit with an integrated measuring head (45 o / 0 o measuring
geometry) for precision colour measurement and control of regular surfaces. The
Lovibond RT200 consists of a similar spectrophotometer unit but with a flexible,
fibre-optic measuring head (0 o / 0 o measuring geometry) for colour measurement of
small areas, challenging shapes or relatively inaccessible places.
The RT100 and RT200 instruments both combine advanced microspectrometer
technology with the computing power of a PC. The spectrophotometer units link to a
standard PC computer with software installed for instrument operation and for
presentation, analysis and logging of reflectance data. Results can be expressed in a
choice of colour values and colour difference measurements.
