Product Overview
The AutroFlame X32AF is a specialized multispectrum infrared detector engineered to detect nearly invisible hydrogen flames.
It monitors the water-band infrared emissions produced by hydrogen combustion, allowing it to detect fires that may generate little or no carbon dioxide. Advanced signal processing provides strong flame sensitivity while rejecting false alarms from sunlight, artificial lighting, lightning and hot equipment.
