Product Details:

Measurement Range0-500 Hazen

Lovibond Tintometer Model F .The Model F is a visual colorimeter designed to optimise the use of Lovibond® glass filters in order to express colour in terms of Lovibond® Red, Yellow, Blue and Neutral.
It is arranged with two adjacent fields of view, seen through the viewing tube, so that the product in the sample field and a white reflective surface in the comparison field are observed side by side, suitably illuminated.
The Lovibond® glasses are introduced into the comparison field by a simple system of sliding racks, allowing the user to compare the colour of light which is either transmitted through, or reflected from, the sample.
A series of neutral glasses in racks is also supplied; these can be introduced into the sample field to ‘dull’ the colour of products which are too bright to obtain a good colour match using Lovibond® Red, Yellow or Blue glasses. The racks allow a visual colour match to be found from the light from the sample and its colour can then be expressed in Lovibond® units.
Lovibond® Tintometer® is the only company that can guarantee accurate, validated Lovibond® RYBN Colour readings.

Application Areas: Food & Beverages, Beers, Malts & Caramels, Edible Oils & Fats, Petroleum Oils & Waxes, Pharmaceuticals & Cosmetics. Kreis Value (Rancidity in Fats), Lovibond® RYBN Colour, A Guide to Path Length by Colour Scale

Interface provides the user with immediate information on the sample:

• EC 2000 Two Field View
• Advance from Visual (subjective) to Electronic (objective) Color Measurement
• Color Measurement
• Display Results with On-Screen Color and Numerical Options

Digital, Portable, Push-Button Technology
• Immediate reporting from lab or on-site

The user friendly ergonomics and intuitive interface guarantee new users can be quickly trained and easily supported. Large data storage (> 20,000 readings), USB connectivity ensures readings can be stored and shared easily and quickly. Flexibility is further enhanced with software packages for Windows® with multiple language support on-screen.

 

 

Lovibond® accuracy and efficiency is apparent throughout. EComparators are supplied with Certified Glass and Liquid Reference Standards enabling quick and simple validation.

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.)

A Flexible, Modular System for Visual Color Grading
We are proud to announce that the Lovibond® Tintometer® Comparator 3000 and Petroleum Oil Comparator (AF650) have now been replaced by one brand new design designated the Comparator 3000/Petroleum AF650.

Our new units are a series of single scale, 3-field instruments for visually determining the color of samples by direct comparison with colored glass filters. With a 3-section field of view, the sample and two consecutive glasses on the color scale are viewed simultaneously, making it easier to achieve the optimum color match. For rapid color grading within predetermined color limits, the glasses can be set to the two limiting colors, making it easy to see if the sample is within tolerance.

 

Scales and Scope:

EBC Comparator : Beers, Malts & Caramels, EBC (European Brewing Convention)

Gardner Comparator: Gardner Color

FAC Comparator: Edible Oils & Fats, Petroleum Oils & Waxes, FAC Color (AOCS Cc13a-43)

Petroleum Oils Comparator: Petroleum Oils & Waxes, ASTM Color (ASTM D 1500, ASTM D 6045, ISO 2049, IP196)

Rosin Comparator : Coatings, Rosin – US Naval Stores (ASTM D 509), Rosin – French (Bordeaux) Color
