The SEC Signature DIR Dual Infrared Gas Analyzer is a self contained dual chamber optical gas analyzer designed for a non-intrusive continuous monitoring of process gases. This infrared optical gas detector is self-compensating for most aging environmental and contamination effects in which results in excellent measurement integrity. The SEC Signature DIR measures infrared light absorption due to molecular resonances. These dual gas analyzers are tuned to the infrared signature of the target gas or vapor, measuring light at wavelengths absorbed by the target gas and at wavelengths not absorbed by the target gas. The gas concentration is determined by calculating the ratios of the analytical and reference levels. These dual gas analyzers are unaffected by humidity and pressure. Embedded linearization algorithms keep the output accurate regardless of the ever changing environmental conditions. This optical gas detector monitors H2O, Hydrocarbons and Carbon Dioxide gas vapors. Patented self-compensating optical bench. Fast response time. This infrared gas analyzer can be used in the medical device industry monitoring their sterilization chambers.
