The HNL Flame Detector is a compact and highly responsive Flame / Fire Detector. The Unit incorporates an extremely sensitive sensing circuit that responds to high energy sources in a bandwidth of 185 260 nm with optimum spectral sensitivity centred around 200 nm.
Thus HNL Flame Detector is the most effective in early detection of a fire before they can possibly cause damage. In contrast, other types of detectors operate at a disadvantage. Smoke detectors do not operate until the fire has developed into a sufficient size to accelerate smoke along with strata of hot air rising to the detector.
It is particularly suitable for use in outdoor applications because it is not affected by wind or rain. Various models
to detect & control the presence or absence of flame are available
