Lovibond® Tintometer® PFXi-880/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® PFXi-880/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.
Remote Calibration & Maintenance Service via internet (RCMSi)
Color measurement instruments need regular checking with calibration standards to ensure correct operation and compliance to established international standards. RCMSi is the process in which a number of tightly controlled calibration liquids are measured in a 50 mm cell* via the Calibration function of a PFXi. The data is communicated via the internet to a secure server and compared to Master Data. If the data passes within tolerance, then a Certificate of Calibration is e-mailed to the user. This allows The Tintometer Ltd to ensure a PFXi instrument is operating correctly and fully calibrated using ISO 17025 certified standards. So, users can be 100% confident that all PFXi readings are reliable. In addition, RCMSi eliminates the timely and costly need to return equipment to a service center unnecessarily.
Note: Please register before performing your first calibration. Certificates of Calibration are provided post process.
*(Please note 50mm cell must be used when performing RCMSi calibration.)
|Color Scales *||Scope||Range||Resolution|
|IP Units||Light colored products such as refined, undyed motor fuel, white spirit or kerosene.||Water White (0.25) to standard White (4.0)||6”|
|Lovibond® RYBN Color||Petroleum products in terms of Lovibond Red,Yellow and Blue units||0 – 70 Red, Yellow; 0 – 40; Blue; 0 – 3.9 Neutral||1 / 16 ” – 5 1 / 4 ”|
|CIE Values (ASTM E308)||X Y Z tristimulus values; x y Y chromaticity coordinates; CIE L*a*b* color space; E color difference||Defined by spectrum locus|
|Spectral data (420 – 710 nm)||Transmittance||0 – 100%||0.01%|
Color Analysis made Simple
The PFXi-880/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 PFXi-880/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.
