Product Overview
The AutroFlame X98AF is an explosion-protected infrared flame detector designed for rapid fire detection in marine, offshore and heavy-industrial environments.
Its Time Domain Signal Analysis technology provides strong immunity against background infrared radiation from heaters, turbines and ovens. It is especially suitable for contaminated or dirty areas where reliable detection and low maintenance are essential.
