The Lovibond ® PFXi-880/F is the ideal solution for anyone wanting to
measure colour only according to the Lovibond ® RYBN Colour Scale. The
latest model in the extremely successful PFXi range focusses only on this
specific scale. The PFXi-880/F provides easy-to-use, press-button technology which requires no special skills to operate. The built-in menu guides users through the selection of operating parameters – such as language selection. Thereafter, readings are made with a single key press, taking less than 30 seconds to complete.
In the 1890’s, Joseph Lovibond, the founder of The Tintometer Ltd,
developed the original Lovibond ® Scale, based on a calibrated series of red, yellow, blue and neutral glasses. RCMSi – Save Time, Effort and Money After more than a century, The Tintometer Ltd still manufactures and grades the glass filters used for visual colour measurement in terms of
Lovibond ® units. It is this unparalleled knowledge and experience that are
embodied into the Lovibond ® PFXi-880/F.
The scale quoted by others as the Lovibond ® scale does not guarantee
validated Lovibond ® Colour readings and may not conform with any visual
instrument for Lovibond ® Colour.
The PFXi-880/F includes RCMSi technology. This unique feature allows
a calibrated measurement to be taken using an ISO 17025 certified
liquid standard. The spectral response is transmitted to the Lovibond ®
secure calibration server. On completion of this procedure, a traceable
calibration certificate is made electronically available to the user. The
RCMSi system not only gives the user added confidence that the
instrument is working within tight ISO standards but also reduces the
need for expensive, on-site servicing and preventative maintenance of
the unit.In contrast, The Tintometer Ltd can provide validation reports of correlation between Lovibond ® values obtained on its automatic instruments and Lovibond ® visual instruments.
Furthermore, the Lovibond ® instruments uniquely include long sample
chambers that house cells of up to a 6” path length, enabling the
instrument to obtain direct Lovibond ® colour readings, without multiplying
errors, with 5 1⁄4” cells.
Automatic Testing vs Visual:
The fundamental difference between the PFXi and the Lovibond ®
Tintometer ® Model F is that the Model F is based on subjective, visual
comparison methods (relying to a high degree on the judgment and skill
of the operator and hence their perspective, feelings, beliefs and desires).
The PFXi, however, relies on automatic, non-subjective measurements,
completely unaffected by the judgment of the operator).
With operators inexperienced in colour measurement, visual comparison
can be more time consuming and less precise than the fast automatic
readings taken with a PFXi. Visual agreement between operators at one
site or multiple sites cannot be guaranteed.
Using spectrophotometers, colour communication is accurate and
reliable and consistent. Colour Scales allow exact standards to be
communicated to all.
