EN-600Ex Explosion - proof Hydrogen Analyzer

OVERVIEW

The EN-600Ex Explosion-proof Hydrogen Analyzer is an analytical instrument developed for online industrial use in hazardous areas. It utilizes gas thermal conductivity, a physical property which measures specific component in mixed gases through difference in thermal conductivity of various gases. 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 H2 volume concentration in the sample gas.

FEFATURES

Used in explosive atmosphere in zones 1 & 2, Class ExdⅡCT6

Long-life, maintenance-free, Micro-fuel Cell oxygen sensor
