The Model 400 Flame Pack is a hydrocarbon gas detector, which employs hydrogen flame ionization as the detection method. The Model 400 is designed to be hand carried as a single unit. It eliminates shoulder straps, harnesses, interconnecting tubes, cords and the like. It is lightweight and small in size. Its moving parts and controls are kept to a minimum, which reduces downtime for repair. It can be taken anywhere a person can walk, crawl, or climb.
 

In the search range, (50 ppm @ full scale), it is capable of detecting as low as one part per million (ppm) of hydrocarbons in air. A centering range, (5000 ppm @ full scale), is provided to assist in centering leaks. The meter indicates the presence of hydrocarbons. An alarm sounds at a preset point on the search range.
 

The Model 400 Flame Pack utilizes disposable 9-volt alkaline batteries, available almost anywhere, and a 40% Hydrogen/60%Nitrogen fuel mixture. The Model 400 Flame Pack is adaptable for mobile applications utilizing auxiliary sampling systems.
