The Lovibond® visual and automated colour measurement instruments: spectrophotometers for transmission and reflectance; colorimeters and colour comparators) are synonymous with accuracy in the analysis of liquids and solids including: petroleum, edible, industrial & fuel oils, chemicals, pharmaceuticals, beverages & foodstuffs. The instruments and ISO17025 certified reference materials comply with international test methods and standards such as ASTM, DIN, AOCS and ISO.
Colour measurement is an important procedure in petroleum processing. Colour is an indication of type and quality. Within this industry, the colour of petroleum is an important indication of the status of the refining process from its crude state to its deliverables. Pricing across the world is set, partly, against the colour of the product. In some applications, colour is also used as a means of recognition as is the case with aviation fuel and ships diesel fuel. Other petroleum products are required to be colourless such as food quality waxes. At Peftec, Stands 46, 47, 48 & 49 , the Lovibond® team will be available to discuss and demonstrate how colour should be measured according to industry standards and scales such as ASTM, AOCS and Gardner to mention just a few.
The Lovibond® team will be demonstrating a range of automatic and visual instruments (and the best of both worlds!) able to measure the colour of petroleum according to the following internationally recognised scales:
Lovibond® RYBN Colour (IP 17 Method A )
ASTM Color (ASTM D 1500, D 6045, ISO 2049, IP196, JIS K 2580)
Dyed Aviation Gasoline (ASTM D 2392)
Gardner Colour (ASTM D 1544, ASTM D 6166, JIS K 2580)
Saybolt Colour (ASTM D 156, ASTM D6045)
Platinum Cobalt / APHA / Hazen Colour (ASTM D 1209)
The extremely popular PFXi Spectrophotometric Colorimeters with their remote calibration and maintenance via internet abilities are deployed across the world in refineries where Very rugged, chemically resistant, steel construction units are required. Easy-to-maintain with removable sample chambers, the instruments are also able to handle hot samples with high maintenance points.
The EComparator series enables you to Advance from visual (subjective) to electronic (objective) Colour Measurement with 2 field (EC 2000) or 3 field (EC 3000) comparator view & numeric results. They guarantee agreement with the International Standards: EC 2000 Pt Co; EC 2000 Gardner; EC 3000 ASTM Colour; and EC 3000 Saybolt.
For visual measurement, you can choose between the dedicated Comparator 3000 POC (petroleum Oils Comparator) or the more tradition Comparator 2000.
All Lovibond® products can be supplied with liquid and/ or glass reference standards and additional accessories such as high quality optical cells.
