Two spectrophotometric colorimeters that each include several of the popular scales that meet the requirements of objective colour analysis of oils, chemicals, fuels and other transparent products. The PFXi 950 instruments are rugged colorimeters with fabricated steel housings, which function equally as QC instruments within the laboratory or on 24-hour operation in a production environment. The accuracy and repeatability of the colour data provided by these colorimeters ensures consistency in colour measurement, giving processors the confidence needed to make important decisions regarding raw materials and refining operations.

• RCMSi provides confidence of calibration and reduces on site servicing and maintenance
• Removes subjectivity of measurement
• Robust instrument for in process and final analysis tasks
• Easy to use
• Large, removable sample chamber for easy cleaning

An integrated heater unit is available as an option for melting solid samples such as fats and waxes preventing them from solidifying in the cell. Each instrument features a long sample chamber for cells up to 153 mm path length, ensuring precise colour measurement even with unsaturated samples such as solvents and white oils.

The RCMSi (Remote Calibration and Maintenance Service via internet) feature allows a calibrated measurement to be taken using an ISO 17025 certified liquid standard. The spectral response is transmitted to The Tintometer Ltd’s secure calibration server. On completion of this procedure, a traceable calibration certificate is e-mailed to the user. A set of standards is included with each meter to allow one RCMSi check at no cost. Subsequent RCMSi checks would be chargeable.

The PFXi 950 colorimeter expresses colour in terms of Lovibond RYBN, AOCS-Tintometer Colour, Gardner Colour, CIE Values, Spectral Data.
The PFXi 950/P Petrochemical colorimeter incorporates the core colour scales for mineral oils and petrochemicals including both Saybolt and ASTM Colour. It also includes Pt-Co/Hazen/APHA scales.

On each instrument results can also be displayed in terms of CIE values and spectral data.
