Lovibond® Tintometer® PFXi-880/P

The Lovibond® PFXi-880/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.

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
Saybolt Color (ASTM D6045, ASTM D156, JIS K2580) Light colored petroleum products including aviation fuels, kerosene, white mineral oils, hydrocarbon solvents and petroleum waxes. -16 (darkest) to +30 (lightest) 1
ASTM Color (ASTM D6045, ASTM D1500, JIS K2580) A wide range of petroleum products including lubricating oils, heating oils and diesel fuel oils 0.5 – 8 units (resolution 0.1 units) 0.1
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%

Brings Precision and Reliability to Color Measurement

The accuracy, repeatability and reproducibility of data provided by the Lovibond® PFXi-/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 PFXi-880/P to obtain precise color measurements, without multiplying errors.

Color Analysis made Simple

The Lovibond® PFXi-880/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 PFXi-880/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 PFXi-880/P, ensuring excellent correlation with visual grading instruments.
