JTH-CH386EX detects the Ultraviolet produced by fire,combines with the flame flicker frequency to process multiple signals ,which can maximum restrain the false alarm and the optimal fire detection perfermance,improve the sensitivity and response time of the detector. The flame detector not only has early warning performance for organic compounds and other organic materials, but also for inorganic fire.

The JTH-CH386Ex explosion-proof point type infrared / UV flame detector can work in harsh industrial environments such as high temperature, low temperature, high humidity and vibration.
