PFX880/IP17
Auto IP Units & Lovibond Color - PFX880/IP17
The Institute of Petroleum’s standard method IP 17 specifies
that the color of petroleum products is determined in terms
of either Lovibond values (Method A), or a restricted range
of 14 color standards IP Units (Method B). The Lovibond PFX880/IP17
is a limited-scale, automatic colorimeter for color measurement
according to both Lovibond RYBN Color and IP Units. Results
can also be displayed in terms of CIE values and spectral
data.

Color Analysis made Simple
The PFX880/IP17 colorimeter is an easy to use, automatic
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. When measuring IP Units of clear, water-white products,
the long sample path length ensures precise color measurements,
without multiplying errors.
Confidence in Instrument Performance
The PFX880/IP17 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 colorimeters are
also supplied with a colored glass filter from the appropriate
color scale.
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 Lovibond
RYBN Color scale or IP Units, are available.
Certified color reference standards
Ideal for routine calibration and verification of test data.
