Lovibond® PFX195/2 Automatic Colorimeter for Petroleum Oils & Fuels

Price: £3,899.00 (£4,581.33 Including VAT at 17.5%)

Standard Colour Scales
Saybolt, ASTM Color, Pt-Co

Colour Testing Made Simple
The Lovibond® PFX195 is an easy to use, automatic instrument that requires no special skills to operate. The built-in menu guides users through the selection of operating parameters such as colour scale. Thereafter, readings are made with a single key press, taking less than 25 seconds to complete.

Easily Customised to User Specifications
Adaptable software and design allow users to configure the PFX195 to their requirements. Operators can set the language for display, program the PFX195 to show only those scales of interest or restrict access to the menu system. As well as standard colorimetry cells, the PFX195 can be used with a range of tubes and standard,
flow-through and disposable spectrophotometer cells.

Calculation and Description of Off-Hue Status
The PFX195 off-hue status is a useful facility that reveals whether the sample colour is characteristic of the selected scale. It includes a description of hue difference (eg. redder, greener), relative saturation (stronger or weaker) and an off-hue factor (a relative measure of the distance away in colour space of the sample colour from the ‘true’ colour scale).

Suited to Laboratory or Production Environments
Comprehensive facilities for colour management make the Lovibond® PFX195 an ideal choice for the laboratory. However, with excellent calibration stability, password protection for tamper proof control and simple operation, the PFX195 also supports the migration of quality control to the manufacturing area, making it a costeffective option for dedicated production testing. For easy maintenance, the Lovibond® PFX195 includes a robust steel sample chamber, which is simply removed and cleaned if a spillage occurs, and the precision filament lamp is easily assessed and changed from outside the instrument.

Optimised Use of Colour Data
Data sets can be saved in the instrument, printed out or automatically downloaded to a PC computer where they can be processed and stored for future analysis, traceability and monitoring trends. The colour control software supplied with the PFX195 enables the generation of spectral and CIE diagrams as well as analysis of
spectral data. It also permits direct control of the instrument from the computer.

Confidence in Colour Measurement
For regular conformance checking each PFX195 is provided with a calibrated glass filter of known colour value. Sets of conformance filters and certified colour reference solutions are also available for routine calibration and verification of test data. Conformance filters are supplied with a Certificate of Conformity stating their colour values and confirming that they have been manufactured and inspected under
the control of Tintometer’s ISO 9001: 2000 quality system. Certified colour reference solutions are supplied with full traceability to internationally recognised standards, either ISO/IEC 17025:2000 (ASTM Color, Saybolt and Gardner Colour) or the ISO 9001: 2000 quality system (Pt-Co Units).
