Progressive Colour Measurement

Special offer from Lovibond Tintometer

Lovibond Tintometer has a long and impressive history having been established in 1885 by Joseph Lovibond, a brewer in Salisbury. Lovibond was amazed that master brewers could tell good beer from its colour. He wanted to ensure that the colour of his beer was always the same, so his customers would know that the high quality was constant. He therefore needed something, a standard, to which he could match the colour of the final brew.

Rumour has it that he was inspired by the beautiful glass windows of Salisbury Cathedral which still had the same glorious colour as on the day it was first installed centuries before. Whatever the inspiration, the permanence of coloured glass suggested itself to him as the ideal colour standard. After much searching, a range of glasses of the right colours was found and thereafter there was no further difficulty in keeping the product up to standard.

This idea was expanded from just measuring the colour of beer. By combining coloured glasses of the three primary colours red, yellow and blue, he realized that you could effectively build up the colour of any object. Lovibond built up a series or “Scale” of these glasses in each of the three colours going from very pale to a very dark and gave a number or value to each glass.

These standard glass colour scales are still in use today and, throughout the world, millions of applications continue to measure colour with visual instruments made with glass still produced in the United Kingdom: whether the traditional Lovibond® Comparator 2000+ system or the three-field Comparator 3000 system.

While visual instruments are still very good and accurate, they do rely on the ability of the user to correctly identify the exact measurement: a judgement that can be impaired by a variety of reasons, not least: colour deficiency; tiredness or personal surroundings.

Automatic instruments, by contrast, offer the following benefits:

Automatic instruments give precise, objective data versus human, subjective data
Automatic instruments require no skill/experience of operators
Automatic instruments offer precise, fast results
Automatic instruments do not rely on the environment (right lighting)
Automatic instruments do not rely on the human eye which can suffer from fatigue
Automatic instruments communicate in clear terms, accurately and reliably
Automatic instruments store results which can then be shared
 

The EComparator series advances colour measurement to enable you to easily progress from Visual (subjective) to Electronic (objective) results; removing any potential ‘fear’ of upgrading to an electronic instrument.

With the EComparator series, you can view the colour difference with on-screen colour and on-screen numerical display. Touch screen technology makes the instruments easily programmable with instinctive menus on screen. You 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) provides the user with immediate information on the sample. EComparators are available to measure ASTM, Saybolt, Platinum Cobalt and Gardner scales

The PFXi series of spectrophotometric colorimeters introduced a unique concept in liquid colour control: RCMSi technology (Remote Calibration & Maintenance Service via internet). You can now benefit from the capability for remote calibration and servicing - eliminating any costs and time delays associated with servicing and guaranteeing compliance with standards.

The PFXi range is supplied with a full variety of colour scales for specific markets including, but not limited to, Petroleum, Edible Oils, Pharmaceuticals, Brewing and Honey. Uniquely, you can also upgrade scales remotely at any time. Some of the product variants are also available with an optional integrated heater unit, a critical feature when dealing with materials such as fats and waxes whose temperature needs to be maintained at a constant temperature +10°C above the "Cloud Point" of the material.

The Lovibond® team is offering a special upgrade package, available from any of our respected international resellers, to all customers currently using a visual colour measurement unit. This offer applies to any Lovibond® glass colour disc in the field today.

So, if you or your customers are currently using a Lovibond® glass colour disc, you can use that disc to receive a significant discount on either the:


Lovibond® EComparator (limited to one disc per instrument)
or
Lovibond® PFXi Series (limited to one disc per instrument)
 

No Need to Return Your Instrument

Unlike other similar campaigns, we are letting you keep your visual instrument too. Simply send us a picture of the disc with the serial number and scale (with a picture of the box too if you still have it), and we shall apply the discount.  (See Figure 1).

Simply send a copy of your photos to sales@tintometer.com and we’ll take it from there.
