Fixed Infrared Gas Analyzer NFIA-350

Fixed infrared gas analyzer NFIA-350 is a fixed model analyzer designed for monitoring, detection and analysis of combustible, toxic, poisonous gases present in severe environmental condition areas. Composed of aluminum alloy and stainless steel making it corrosion resistant. Equipped with control panel for remote controlled monitoring of large analysis area. Built-in alarm and fault relay system facilitates personnel and plant protection from flammable, toxic and oxygen hazards.
