Gas Analyzers
The 7300 series can be provided in a variety of configurations
7300A - Flush panel or rack mount
7300B - NEMA 4 wall mount (suitable for Div. 2 or Eex(p) purge)
7320 - Full explosion proof design (Class I, Division 1, Group B)
The design of these analyzers eliminates the traditional motor driven chopper wheel, signal conditioning circuitry and complex optics resulting in a compact and rugged analyzer. The optical detection bench has been qualified for critical life support systms in space suits, shuttles and space station Freedom.
