Lovibond: PFX880/P - Automatic colorimeter



Description

The Lovibond® PFX880/P is a high precision spectrophotometer for objective colour 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.
The Lovibond® PFX880/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.
The PFX880/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.

Instrument is supplied with:
 - Two glass cells 1x33mm, 1x100mm.
 - Calibrated glass conformance filter (Saybolt +10)
 - Reference material for Saybolt (+12) and ASTM Color (3)
 - Spare lamp
 - Instruction manual
