In refined petroleum products, color variations indicate impurities and/or the presence of trace water or haze. This contamination can be a significant liability as color differentiation can be easily detected by the end user. The CHA Colorimeter/Haze Analyzer is the ideal qualitative solution for monitoring both the color of refined products, including those with added dyes, and the presence of haze or turbidity in pipelines following the refining process. In addition, it can be used as quality control with water treatment.

Utilizing a unique 5-LED design, the CHA detects color variations within 1%, and unlike most colorimeters, it can detect the entire range of visible color as defined by CIE 1931 (International Commission on Illumination). Final color measurement can be expressed as haze plus three color (X, Y, Z) or one of several industry-standard color scales including, Saybolt, Platinum and Cobalt, and ASTM.

Turbidity or haze measurement allows refineries and pipeline operators to identify and redirect non-conforming batches.

Measurement is fully automatic, and the CHA Colorimeter/Haze Analyzer does not require site calibration. It employs long lasting LED light sources ensuring long-term, stable performance with limited maintenance and power requirements. In addition, locating the electronics within an explosion-proof enclosure directly on the atmospheric end of the optical probe creates a complete and compact unit with maximum installation flexibility. The CHA easily installs where other colorimeters, weighed down by large electronics/computer units, cannot.

A paper on Interface Detection in Liquid Pipelines, including the CHA, was presented at the International School of Hydrocarbon Management in Oklahoma City, Oklahoma.
