PFX995/P    Petrochemical Tintometer
The Lovibond PFX995/P is a spectrophotometric colorimeter that is designed to meet the colour analysis requirements of petroleum fuels, oils, waxes and petrochemicals. It provides objective, unbiased colour data according to a full range of established industry scales, although the user can easily customise the PFX995/P to display only those scales of interest. Measurements can also be displayed in terms of spectral data and CIE values.

PFX880/IP17    Auto IP Units & Lovibond Colour
The Institute of Petroleum?s standard method IP 17 specifies that the colour of petroleum products is determined in terms of either Lovibond values (Method A), or a restricted range of 14 colour standards IP Units (Method B). The Lovibond PFX880/IP17 is a limited-scale, automatic colorimeter for colour measurement according to both Lovibond RYBN Colour and IP Units. Results can also be displayed in terms of CIE values and spectral data.

Tintometer Model F   
The Lovibond Tintometer is a visual colorimeter for measurement of practically all petroleum products in terms of Lovibond units according to IP 17 Method A. Colour is determined by comparing the light transmitted through the sample with that transmitted through Lovibond Colour standards - a series of accurately calibrated coloured glasses in each of the colours red, yellow and blue, going from very pale to dark- Waxes are measured for colour either by transmitted light when in a molten condition or by reflected light when solid.The Model F is supplied with a complete set of 11 racks containing the Lovibond Colour standards (Red 0. 1 - 0.9, 1.0 - 9.0, 10.0 - 70;Yellow 0. 1 - 0.9, 1.0 - 9.0, 10.0 - 70; Blue 0. 1 - 0.9, 1.0 - 9.0, 10.0 - 40; Neutral 0. 1 - 0.9, 1.0 - 3,0), a sample chamber liner with a white PTIFIE reference, a spare white reference, rectangular fused glass cells, a colour analysis records book and instructions.

Certified Colour Reference Standards for Oils, Fuels & Chemicals   
These CRMs are ideal for routine calibration of colour measuring instruments, verification of test data and ensuring good inter-laboratory or inter-instrument correlation. The range of liquid standards includes AOCS-Tintometer, ASTM, Gardner, Lovibond RYBN, Pt-Co and Saybolt Colour, the key colour scales applied to oils, fuels & chemicals. They are supplied with full traceability to internationally recognised standards, either UKAS to ISO 17025 (ASTM, Gardner & Saybolt Colour) or the ISO 9001 quality system (AOCS-Tintometer, Lovibond RYBN & Pt-Co Colour). Each standard comes in a 500 ml bottle with a 12-month guarantee of colour stability and full certification including MSDS.

Conductivity Standards   
Conductivity has a wide range of applications and is used in various industries including, semiconductor manufacturing, power generation, chemical, pharmaceutical, food and beverage processing, metal and mining, textiles, pulp and paper and environmental monitoring of water quality. In most cases conductivity is an aqueous based test where it proportionally reflects the degree of water purity, the lower the conductivity of water the higher it?s purity. The measurement of low level conductivity in particular has been fraught with difficulties due to the lack of a calibration standard which is stable, matrix matched and with a certified accuracy. We can now offer a range of conductivity standards with values ranging from 1.3 ÁS/cm to 500,000 ÁS/cm.

Refractive Index Standards   
Paragon Scientific produces a range of sucrose standards for use in the calibration and verification of all types of refractometer e.g. handheld, Abbe and high accuracy digital instruments. Sucrose standards are manufactured using traceable high purity materials to four decimal places following ICUMSA methods. They are the only standards available world -wide which carry a full BS EN ISO / IEC17025 certificate of calibration with each bottle. Sucrose solutions are ideal for use in the food and beverage industries and are available in various concentrations depending on the end users application. Unique concentrations can also be manufactured upon request.
