Compact Triple-Band UV/IR Flame Detector for Hazardous Industrial Areas

The Triple-Band UV/IR Flame Detector is a compact and high-performance solution designed for hazardous industrial environments. Combining narrow-band infrared sensors and a "solar blind" ultraviolet sensor, this detector delivers accurate flame identification while effectively rejecting false alarms from common interference sources. Built with a modular core and corrosion-resistant coated aluminum housing, it ensures easy maintenance and long-term durability. With a wide 120° viewing angle and fast response time, this detector meets GB12791, GB15631, and GB3836 standards, making it suitable for oil, gas, chemical, and other high-risk applications.
