  • Page 6: Principle Of Operation

    13, weight: 9kg IV. Principle of operation: The test of HC, CO and CO via HPC500/400 Auto Exhaust Analyser, which adopts nondispersive infrared ray analytical method (NDIR), is based on the principle that different gases selectively absorb infrared rays. The Instrument, by adopting narrowband infrared interference filter, is capable of analysing the content of required gas from tested gas, and therefore has good selectivity.
