Objective colorimetric data for process control

Lovibond® PFXi-880, PFXi-950 and PFXi-995 instruments are accurate and highly efficient spectrophotometers, suitable for optically transparent samples, which satisfy the need for constant and reliable colour data for a wide range of samples. The long path cell chamber allows the measurement of clear, extremely unsaturated samples and also of colour scales defined with long path lengths, including Lovibond® RYBN and AOCS Tintometer® colours. Instruments remove all subjectivity involved in colour measurement, providing error-free readings not influenced by the operator or the environment. 

Wide selection of standard colorimetric values

The PFXi-880/950/995 Series of colorimeters automatically measures colour and displays results directly or according to traditional colour scales, largely adopted as industrial standards for colour assessment and control, or in terms of internationally recognised CIE values and spectral data: The upgrades of colour scales provide flexibility to comply with individual requirements, allowing to add further colour scales to instrument standard version, both at the order placement or remotely, once the instrument is operating. For products that are incompatible with standard colour scales, the PFXi series allows users to build a customised scale from a series of reference samples and then obtain the closest concordance to stored references.

RCMSi Technology (Remote calibration and maintenance service via internet)

PFXi series includes new RCMSi Technology (Remote calibration and maintenance service via internet). This unique feature allows to acquire a calibrated measurement using an ISO 17025 certified liquid standard The spectral answer is transmitted to safe Lovibond® calibration server. At the end of this procedure, a traceable calibration certificate is electronically available for the user. RCMSi system not only gives the user greater confidence about instrument operation within the severe ISO standards, but also reduces the need for an expensive in-situ assistance and preventative maintenance of the unit.

Colour analysis made simple

The PFXi Series provides automatic, easy to use instruments, which do not require any special skill to operate them. The integrated menu drives users through the choice of operation parameters such as the colour scale. After that, readings are performed by only pressing the button once and requiring less than 30 seconds to complete them. Built-in help files are available.

Easily customised to user's specifications

The adjustable software and design allow the users to configure PFXi Series to their requirements. Operators can set up the displayed language, program PFXi to only show interesting scales or to limit the system menu access. As with standard colorimetry cells, PFXi can be used with a range of tubes and cells for standard, flow-through and single-use spectrophotometer.

Calculation and description of off-hue status

The PFXi range off-hue status is a useful feature which reveals whether the sample colour is characteristic of the selected scale. Where appropriate, it includes a description of the hue difference (e.g redder, greener), of the relative saturation (stronger or weaker) and a off-hue factor (a relative measurement of the gap in the colour space of the sample colour from the "real" colour scale).

Adapted to laboratory or production environments

The global features for colour handling make the PFXi Series an ideal choice for your lab. However, with its excellent calibration stability, the password protection for the anti-tampering control and the easy operation, the PFXi range also supports migration of quality control to production area, making it a cost-saving option for dedicated analyses in production. For an easy maintenance, Lovibond® PFXi Series includes a sturdy steel sample chamber, easily removable and cleaned in case of spillover; the filament precision lamp is easily accessible and replaceable from the outside.

Optimized use of colour data

Data sets can be saved in the instrument, printed or directly downloaded to a PC, where they can be processed and stored for future analysis, traceability and trend monitoring. The colour control software provided with PFXi allows to generate spectral and CIE diagrams, as well as spectral data analysis. It also allows the direct instrument control from computer. Confidence in colour measurement For a regular conformity verification, certified colour reference standards are also available, for routine certification and analysis data verification. Conformity filters are provided with a Compliance Certificate which states their colour values and confirms they have been produced and inspected according to ISO 9001 quality system of The Tintometer Ltd. The certified colour reference standards are provided with complete traceability.
