Flame Out Indication: Light emitting diode (LED) and audible Alarm
Sample Flow Rate: 220-240cc/min
The Model 400 Flame Pack is a hydrocarbon gas detector that 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, and cords. It is lightweight and small. Its moving parts and control s 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 can detect 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.
