Objective Color Data at an Affordable Price

The Lovibond® PFXi-195 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.

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.)

Comprehensive Selection of Standard Color Values

PFXi-195 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 PFXi-195 is configured as a series of industry-focused instruments, each including the principal color scales used in that sector. We supply the following:

Version Application Standard Color Scales
PFXi195/1 Liquid chemicals & industrial oils Pt-Co/Hazen/APHA, Gardner, Iodine, CIE values, spectral data
PFXi-195/2 Petroleum oils & fuels Saybolt, ASTM Color, Pt-Co/Hazen/APHA, CIE values, spectral data

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 PFXi-195 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® PFXi-195 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 complete.

Easily Customized to User Specifications

Adaptable software and design allow users to configure the PFXi-195 to their requirements. Operators can set the language for display, program the PFXi-195 to show only those scales of interest or restrict access to the menu system. As well as standard colorimetry cells, the PFXi-195 can be used with a range of tubes and standard, flow-through and disposable spectrophotometer cells.

Calculation and Description of Off-Hue Status

The PFXi-195 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® PFXi-195 an ideal choice for the laboratory. However, with excellent calibration stability, password protection for tamper proof control and simple operation, the PFXi-195 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® PFXi-195 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 PFXi-195 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 PFXi-195 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 PFXi-880/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 PFXi-880/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.
