K27580 Automatic Petroleum Refractometer w/ Touch Screen

Description

Test Method

Refractive Index is a fundamental physical property that is used in conjunction with other properties to characterize pure hydrocarbons and their mixtures. It is a useful property for concentration measurements, purity determinations and chemical identification.

Features

Conforms to ASTM D1218, D1747, D5006, and D5775 test specifications

Electronic heating and cooling twin Peltier system operates from 10 to 100°C, eliminating the need for a circulating water bath

Automated and precise refractive index measurements

Detection of correct sample loading with warning message

Monitors cleaning between samples and warns if it the instrument is not cleaned correctly.

Designed for samples ranging from clear to highly colored, dark and opaque

Measures to the fifth decimal place refractive index or hundredths place in percent solids

Multipoint calibration routines maximize accuracy

Automatic detection of temperature and reading stability

Full networking capability with direct data transfer into

Excel, .pdf and other formats

Description

The Koehler Automatic Refractometer uses precision optics and superior image analysis to extend the repeatability and accuracy of refractive index measurements for petroleum products. Subjectivity is removed from tests results because no manual activities such as aligning shadowlines or reading analog scales are necessary. Opaque hydrocarbons present no problem for this unit which uses reflected light measurement technology as opposed to manual refractometers which are of the transmission type. The refractometer incorporates numerous innovations designed to improve the accuracy of petroleum product testing. A linear scanned diode array shadowline sensor is sensitive enough to read even the most demanding samples. A 589 nanometer filter gives true Sodium D-Line refractive index readings. A built-in twin Peltier heating and cooling system gives the instrument the capability of reading at up to 100°C without the need for an accessory water bath. The measuring system guides the operator through every step of the process, advising if enough sample has be used and if it’s placed correctly, providing information about the cleaning process and if residue has been left behind. Set-up, diagnostic and calibration routines are displayed with easy to follow step-by-step instructions. User-developed customer calibration curves may be programmed allowing automatic temperature correction, direct percent concentration, percent reaction completion, etc. This unit has been used successfully throughout the petrochemical industry.
