Model 7600 - Teledyne Analytical Instruments

Infrared Gas AnalyzerIntroductionIntroduction1.1 OverviewThe Model 7600 Infrared Gas Analyzer is a microprocessor basedinfrared gas analyzer used to measure the concentration of NO, SO 2 ,CO 2 , CO and CH 4 contained in sample gas. It is based on the principlethat different molecular species have unique absorption spectrum in theinfrared, and the intensity of absorption is determined by the Lambert-Beer law.In addition to the infrared analyzer, the Model 7600 can also beequipped with a built-in compact paramagnetic O 2 sensor or employ anexternal zirconia oxygen sensor to increase to 5 the number ofsimultaneous component species the unit can analyze.Teledyne's Series 7600 Infrared (IR) Gas Analyzer is convenientlypackaged in either a 19" rack mount or NEMA-4 wall mount enclosure.The NEMA-4 enclosure can be X or Z-purged to satisfy hazardous areainstallation requirements.A high-sensitivity mass flow type twin detector is used for infraredmeasurements. By utilizing a single beam, double path design inconjunction with a serial dual-layer transmission detector, the Series7600 delivers long term, drift-free performance.The concentration of the desired gases is displayed on a large, easyto-readback-lit LCD. Figure 1-1 shows the standard rack mountableModel 7600. The user interface is very intuitive and the menu / modeselection buttons, which are readily accessible, provide the operator withdynamic control and extensive diagnostic capabilities.1.2 Main Features of the AnalyzerThe Model 7600 Infrared Gas Analyzer is designed for accurateand reliable gas analysis and is easy to operate.
