The JR750/UVIR4 five-band ultraviolet-infrared composite flame detector is a high-speed optical flame detector that can respond quickly to hydrocarbon and non-hydrocarbon flames. At the same time, it can eliminate a large number of false alarm sources and can detect a variety of false alarm sources. Provides reliable and continuous protection in existing indoor or outdoor environments.
