007004-HW-Dräger-004
Overview
A robust gas detection solution designed for continuous monitoring of flammable gases and vapours. It operates using the heat-of-reaction principle, where combustible gases oxidise on the sensing element and generate a measurable temperature change. Built for demanding conditions, it maintains reliable performance even in harsh industrial environments.
