JNHT-4 explosion-proof integrated UV flame detector is a UV flame detection device designed and manufactured using UV detection technology based on relevant standards and specifications of the Ministry of Electric Power, summarizing and absorbing the experience of similar products at home and abroad. It uses a new type of ultraviolet photosensitive element, which has the advantages of high sensitivity, convenient operation, reliable performance, and long service life. Integrate all electronic equipment of the flame detector, from the sensor to the signal interface, into the housing of the flame detector. It can continuously detect the flame of various gas fired boilers for a long time, and is an essential detection device for various gas fired boiler safety monitoring systems.
