PFX880/P
Automatic Saybolt & ASTM Color - PFX880/P
The Lovibond PFX880/P is a high precision spectrophotometer
for objective color analysis of petroleum fuels, oils, waxes
and petrochemicals according to the Saybolt and ASTM Color
scales. 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 PFX880/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 Color of clear, water-white products, the long sample
path length enables the PFX880/P to obtain precise color measurements, without multiplying errors.
Color Analysis made Simple
The Lovibond PFX880/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 PFX880/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 which 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 PFX880/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 scales, are available.
Certified color reference standards
Ideal for routine calibration and verification of test data.
ASTM and Saybolt standards are supplied with full traceability
to UKAS
to ISO 17025.
