PFX995/P
Lovibond PFX995/P Petrochemical Tintometer
The Lovibond PFX995/P is a spectrophotometric colorimeter
that is designed to meet the color analysis requirements
of petroleum fuels, oils, waxes and petrochemicals. It provides
objective, unbiased color data according to a full range
of established industry scales, although the user can easily
customize the PFX995/P to display only those scales of interest.
Measurements can also be displayed in terms of spectral data
and CIE values.

Brings Precision and Reliability to color Measurement
The accuracy, repeatability and reproducibility of data
provided by the Lovibond PFX995/P allow for tighter color
specifications and greater color consistency, giving companies
the confidence needed to make important decisions regarding
high value consignments and refining operations. When measuring
Saybolt or Pt-Co color of clear, water-white products, the
long sample path length enables the PFX995/P to obtain precise
color measurements, without multiplying errors.
Color Analysis made Simple
The Lovibond PFX995/P is an easy to use, automatic instrument. There
is no need to build up calibration curves as they are already
established in the instrument. The menu system guides operators
through the selection of operating parameters. Thereafter,
measurements are initiated by just a single key press and
take less than 25 seconds to complete. The PFX995/P is supplied
with a Windows software program, allowing data sets to be
automatically downloaded to a PC computer where they can be
processed or stored. It also permits remote control of the
instrument.
Confidence in Instrument Performance
The PFX995/P is a rugged colorimeter with a fabricated steel
housing, which is designed to function equally as a QC instrument
within the laboratory or on 24 hour operation in a production
environment. A diagnostic test routine and status report allows
users to conduct periodic checks on the instrument or identify
faults. For regular conformance testing the PFX995/P is also
supplied with a certified glass filter of specified Saybolt
value. Tintometer - A Century of Excellence in color Measurement
