The Lovibond® PFXi-995/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 PFXi-995/P to display only those scales of interest. Measurements can also be displayed in terms of spectral data and CIE values.
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.)
Bringing Precision and Reliability to Color Measurement
The accuracy, repeatability and reproducibility of data provided by the Lovibond® PFXi-995/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 PFXi-995/P to obtain precise color measurements, without multiplying errors.
Color Analysis Made Simple
The Lovibond® PFXi-995/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 PFXi-995/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 PFXi-995/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 PFXi-995/P is also supplied with a certified glass filter of specified Saybolt value.
