Our company is an agent of China Japan HAMAMATSU company's main area of ??UV light meter special UV sensor G5842, fire alarm flame sensor R2868 supporting fire equipment manufacturers, the company stock in Japan HAMAMATSU C3704 R2868 flame sensor detection module, R2868 called flame discoverer momentary Mars can be accurately detected, and the corona phenomenon of high transmission of non-visible light can be completely removed .Hamamatsu R2868 is the use of ultraviolet light through the photoelectric effect TRON and gas multiplication effect of the metal source to find Mars. It can detect 185-260 narrow spectral sensitivity different sources. It is no visible light sensor and does not require any visible light filter (unlike semiconductor detectors). It has a small volume and a very wide angle sensitive (optional directional). and can be found quickly and accurately by weak ultraviolet light emitted from the flame (5 m can be detected at a distance or find a cigarette point size of the flame.)
