Objective Color Data at an Affordable Price

The Lovibond PFX195 is an economical colorimeter for optically clear samples that meets the demand for consistent and reliable color data. It removes all subjectivity involved in color grading, supplying unbiased readings that are unaffected by operator or environment.

Comprehensive Selection of Standard Color Values

PFX195 colorimeters automatically measure color and display the results directly, either according to the traditional grading scales that have been widely adopted as industry standards for color assessment and control, or in terms of internationally recognized CIE values and spectral data:

Versatile and Flexible Application

The Lovibond PFX195 is configured as a series of industry-focused instruments, each including the principal color scales used in that sector. We supply the following:

Color scale upgrades give the flexibility to meet individual requirements, enabling additional color scales to be added to standard instrument versions, either at the time of order or remotely once the instrument is in service. For product types that are incompatible with standard color scales, the PFX195 allows users to build up a customized scale from a series of reference samples and then to obtain a closest match to the stored references.

Color Testing Made Simple

The Lovibond PFX195 is an easy to use, automatic instrument that zeros on air and requires no special skills to operate. The built-in menu guides users through the selection of operating parameters such as color scale. Thereafter, readings are made with a single key press, taking less than 25 seconds to com-plete.

Easily Customized 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 color 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 color space of the sample color from the ‘true’ color scale).

Suited to Laboratory or Production Environments

Comprehensive facilities for color 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 cost-effective 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.

Optimized Use of Color Data

Data sets can be saved in the instrument, printed out or automatically down loaded to a PC computer where they can be processed and stored for future analysis, traceability and monitoring trends. The color 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 Color Measurement

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

Color Analysis made Simple

The PFX880/IP17 colorimeter is an easy to use, automatic 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. When measuring IP Units of clear, water-white products, the long sample path length ensures precise color measurements, without multiplying errors.

Confidence in Instrument Performance

The PFX880/IP17 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 colorimeters are also supplied with a colored glass filter from the appropriate color scale.
