FGARD UVIR
The Crowcon FGard UVIR flame detector is an explosion-proof ultraviolet-infrared flame detector, offering superior detection of hydrocarbon fires which are not detectable in the visible spectrum. With adjustable sensors, the Fgard UVIR can be adapted to suit your space, and is capable of operating in even the harshest conditions.
Hvor kan man købeTailor made to detect hydrocarbon flames outside the visible spectrum, the FGard UVIR flame detector is an explosion proof ultraviolet-infrared flame detector designed to provide elite detection of hydrocarbon fires.
The Fgard UVIR incorporates the latest IR flame detection algorithms to prevent the risk of false alarms, and with three different sensitivity settings, you can customise the sensors for your space and needs.
Designed to operate in all conditions, the microprocessor controlled heated optics ensure continuous operation even in harsh weather environments at risk of snow, ice, and condensation.
With advanced optical verification, an automatic test verifies cleanliness of the lens and electronic circuitry to ensure the detector is always primed for optimal performance, requiring no reflector optical check. Plus, its large optical surface minimises the risk of false alarms, so you can respond efficiently with confidence to any alarm.
