北京蓝景世纪科技R2868,13 年批号新到货,全新原装,假一罚十。
These are ultraviolet sensors that utilize the photoelectric effect of metal gas multiplication effect. Flame sensors have high sensitivity a wide field of view (directivity) that allow them to swiftly reliably detect the weak ultraviolet rays emitted from flames (fexample, flame from cigarette lighter more than 5 meters away). This feature makes them ideal as flame detectors fire alarms.
