This manual provides detailed instructions on how to use and maintain the Quasar 900 Open-Path Gas Detection System.
The Spectrex Quasar 900 Open-Path Gas Detection System is designed for the simultaneous detection of C1-C8 flammable gases. The system utilizes a flash source and a detector unit to measure gas concentrations over a distance, with detection ranges varying by model configuration from 23 feet to 265 feet. It features a microprocessor-based design with spectral response between 2.0 and 3.0 microns.
