The
RT series offers a choice of compact, reflectance colorimeters, giving
spectral data for quality control of surface color. The Lovibond RT100
consists of a hand-held spectrophotometer unit with an integrated measuring
head (45° / 0° measuring geometry) for precision color measurement
and control of regular surfaces. The Lovibond RT200 consists of a similar
spectrophotometer unit but with a flexible, fiber-optic measuring head
(0° / 0° measuring geometry) for color 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 color values and color difference measurements.
