Gas Analyzers

Model 7300

Infrared Gas Analyzer

Description

The 7300 series of non-dispersive infrared (NDIR) gas analyzers feature fast response, high accuracy, sensitivity, stability and excellent linearity. The cost competitive measurement solutions are due in part to the uniquely designed patented IR detector. The heart of these microprocessor-based analyzers is a temperture compensated, hermetically sealed, steady state thermopile detector integrated into an IR photometric bench.

Configurations

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.
