Ambient Oxygen Monitor

Ambient Oxygen Monitor – Overview

The Gasenz is designed to detect deficient atmospheres in any work area where the risk of asphyxiation may occur due to the presence of gases like nitrogen, carbon dioxide, argon or helium. It is suitable for personnel protection in the gas generation industry, laboratories with gas chromatographs and in hypoxic fire prevention systems, and other industries where industrial gases are stored or used. It is also ideal for use in confined spaces or in hypoxic fire prevention systems. It is a compact and rugged percentage oxygen zirconia oxide or electrochemical sensor oxygen monitor.
