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.
SPECIFICATIONS Measuring principle：Thermal conductivity
Electronic control unit dimensions: 150 × 150 × 258mm
