EN-500Ex (ppm O2)Explosion - proof Trace Oxygen Analyzer

OVERVIEW

The EN-500Ex Explosion-proof Oxygen Analyzer is an analytical instrument developed for online industrial use in hazardous areas. It adopts high performance electrochemical gas sensor and microprocessor technology. The analyzer has such function as isolated current output, relay alarm output, communication interface and measured data storage. It continuously measures, displays, and records trace oxygen in nitrogen, argon, helium and many other reducing gases such as hydrogen.
