Lovibond PFX950/P Petrochemical Tintometer
The Lovibond PFX950/P is a high precision spectrophotometer
incorporating the core color scales for
mineral oils and petrochemicals. It includes both Saybolt Color
and ASTM Color, scales that are
accepted internationally for oil analysis, as well as Platinum-Cobalt
Color for oil derivatives and
petrochemicals. Results can also be displayed in terms of
CIE values and spectral data.

Brings Precision and Reliability to Color Measurement
The accuracy, repeatability and reproducibility of data provided by the Lovibond PFX950/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 PFX950/P to obtain precise color measurements, without multiplying errors.
Color Analysis made Simple
The Lovibond PFX950/P is an easy to use, automatic instrument, which eliminates time-consuming
procedures of visual methods. 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.
Confidence in Instrument Performance
The PFX950/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 allows users to conduct periodic checks on
the instrument or identify faults. For regular conformance testing the colorimeter is also
supplied with a colored glass filter of known Saybolt value.
Tintometer - A Century of Excellence in Color Measurement
Tintometer is recognized around the world as a leading supplier of equipment for
color analysis.
Over the years the Lovibond name that appears on its instruments has become a hallmark for
color measurement, acknowledged by the widespread use of Lovibond systems in process
industries. This unparalleled knowledge and experience are embodied in the Lovibond PFX950/P,
ensuring excellent correlation with visual grading instruments.
Optional Items for Individual Applications
Integrated heater unit
A factory fitted option to prevent heated samples such as waxes
from solidifying in the cell.
Windows software for data capture on PC
Allows data sets to be automatically downloaded to a PC
computer where they can be processed or stored.
Conformance filter sets
For quick and simple conformance checks, sets of graded glass
filters, representing a spread of colors from the Saybolt, ASTM
Color or Pt-Co scales, are available.
Certified color reference standards
Ideal for routine calibration and verification of test data.
