EN-640 Sulfur dioxide analyzer

OVERVIEW

EN-640 sulfur dioxide analyzer is an industrial-used fixed installation type analyzer. It utilises gas thermal conductivity, a physical property which measures specific component in mixed gases through that gases have different thermal conductivities. The analyzer has such function as isolated current output, relay alarm output, communication interface and measured data storage. It continuously measures, displays, and records the SO2 volume concentration in the sample gas. The analyzer is used widely in fertilizer, metallurgy, printing and dyeing, chlor-alkali, petroleum, paper-making industries.FEATURES

With excellent reliability, high-sensitivity, low drift
No requirement for a reference gas during operation
Big LCD display, English or Chinese menu to operate
Automatic recording of measured data and curve, for checking previous data
One isolated, linearized 0~10 or 4~20mADC output
