Lovibond PFX950/P Petrochemical Tintometer

The Lovibond PFX950/P is a high precision spectrophotometer incorporating the core color scales for mineral oils and petrochemicals. It includes both Saybolt Color and ASTM Color, scales that are accepted internationally for oil analysis, as well as Platinum-Cobalt Color for oil derivatives and petrochemicals. Results can also be displayed in terms of CIE values and spectral data.

Color Scales *	Scope	Range	Resolution
Saybolt Color (ASTM D6045,	Light colored petroleum products including aviation fuels, kerosene,	-16 (darkest) to +30 (lightest)	1
ASTM D156, JIS K 2580)	naphthas, white mineral oils, hydrocarbon solvents and petroleum waxes
ASTM Color (ASTM D6045, ASTM D1500, JIS K 2580)	A wide range of petroleum products including lubricating oils, heating oils and diesel fuel oils	0.5 - 8 units	0.1
Pt-Co/Hazen/APHA (ASTM D1209)	Clear liquids such as petroleum spirits, solvents and alcohols	0 - 500 mg Pt/l	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, (full spectrum & specified wavelengths)	0 - 100%	0.01%

Brings Precision and Reliability to Color Measurement

The accuracy, repeatability and reproducibility of data provided by the Lovibond PFX950/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 PFX950/P to obtain precise color measurements, without multiplying errors.

Color Analysis made Simple

The Lovibond PFX950/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 PFX950/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 that 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 PFX950/P, ensuring excellent correlation with visual grading instruments.
