The PFXi series of spectrophotometric colorimeters introduces a unique concept in liquid colour control: RCMSi technology (Remote Calibration & Maintenance Service via internet). Users can benefit from the capability for remote calibration and servicing via the internet - eliminating any costs and time delays associated with servicing and guaranteeing compliance with standards. The PFXi range is supplied with a full range of colour scales for specific markets including, but not limited to, Petroleum, Edible Oils, Pharmaceuticals, Brewing and Honey. Users can upgrade scales remotely at any time. Every PFXi is supplied with colour control software for data analysis (LAN & USB cable provided). Optical glass cells, a certified glass calibration filter, a spare lamp and user instructions included. The PFXi-880 and -995 series are available with an optional integrated heater unit. (This is not available for the PFXi-195). This is a critical feature when dealing with materials such as fats and waxes where temperature needs to be maintained at a constant temperature +10°C above the "Cloud Point" of the material.
Please Note: CIE values and spectral data readings are standard on all the instruments listed below.

A large selection of water test discs are available for colorimetric chemical analyses and colour classification. Each test disc is equipped with fade-free, non porous glass filters, the quality of which is not impaired by UV light or other environmental influences.

Test discs whose code begins with "N", are designed for use in the Nessleriser 2150. Test discs which start with the letter "C" are designed for use in the Nessleriser 2250. All other test discs are designed for use in the comparator 2000+ . The most popular water test discs feature in the table below. Other test discs are available on request.

Two-Field and Three-Field Comparator View and nummerical results. The EComparator series offers the progress from Visual (subjective) to Electronic (objective) results.
With the EComparator series, viewers can view the colour difference with on-screen colour and on-screen numerical display. Touch screen technology makes the EComparator easily programmable with instinctive menus on screen. Users can set language, date and time, view preferences and create projects with individual tolerance settings "within tolerance" (green), "outside tolerance" (red) and "on border of tolerance" (amber) to provide the user with immediate information on the sample.

• Instant and accurate, ready for immediate use
• Guaranteed agreement with international standards
• Results shown on display optional as colour or numeric value
• Digital, mobile technology at the press of a button
• Instant reporting from the laboratory or on site

The EC 2000 range provides users with a Two Field View visual representation in alignment with the popular Lovibond^® Comparator 2000+ system widely used today.

Lovibond^® Comparator 2000+ is a quality instrument for the visual analysis of colour intensity in analysis samples using Lovibond colour discs. The integral cell attachment enables cells with a depth of 40mm to be accepted. The Lovibond^® Nessleriser system provides greater depths by using corresponding accessory Nessler tubes. This enables the determination of concentrations below the detection limit of the Lovibond^® Comparator 2000+. The integral prism in the Lovibond^® Comparator 2000+ brings the glass standard of the colour discs and the colour samples optically into the field of view. The prism is hermetically sealed, preventing the lens from being contaminated. Both the Comparator 2000+ and the Nessleriser are designed in such a way that they compensate for cloudy or coloured water samples. Each device is available for use in daylight or in combination with the artificial daylight unit 2000.

Visual comparators for colour grading. A series of 3-field instruments designed for visual colour grading by direct comparison between the sample and coloured glass standards. The sample and two adjacent glasses on the colour scale are viewed simultaneously, making it easier to achieve the optimum colour match. The tungsten halogen light source is colour corrected to CIE Standard Illuminant C (B for the EBC Comparator 3000) and guarantees constant lighting conditions for colour grading. Versions of the Comparator 3000 are available for the following scales, each supplied with the appropriate range of colour standards and sample containers:

Type	Typical Applications
Gardner Comparator 3000:	Chemicals and oils including resins, varnishes, drying oils and fatty acids (ASTM D1544; ISO 4630, AOCS Methods Ja 9-87, Td 1a-64, Td 3a-64).
Petroleum Oils Comparator (AF 650):	Petroleum oils and fuels (ASTM D1500; IP 196; DIN 51 578; ISO 2049; BS 5859)
EBC Comparator 3000:	Beers, malt worts, caramels and similarly coloured liquids (Analytica)

The Model F is a versatile visual colorimeter for measuring the colour of liquids, solids, powders and pastes in terms of Lovibond units. The user simultaneously compares the colour of light that is either transmitted through or reflected from the sample with that transmitted through a series of glass colour filters in 3 primary colours - red, blue and yellow. The slides are adjusted until a visual colour match is found for the light from the sample and the colour is then expressed in Lovibond RYBN units.

The Model F is supplied with a complete set of Lovibond coloured glass filters (Red 0.1 to 70; Yellow 0.1 to 70; Blue 0.1 to 40; Neutral 0.1 to 3.0), a sample chamber insert for easy cleaning, fused glass cells (one each of 1" and 5¼"), accessories and instructions. An optional solid sample accessory pack is available for measuring light-reflecting products. Includes a 12 Volt a.c. power pack switchable to suit 110/220/Volt supply.
