Expression of performance of gas analyzers - Photometric analyzersScope and object This part of IEC 61207 applies to all aspects of analyzers using photometric techniques for the measurement of concentration of one or more components in a mixture of gases or vapors. It should be used in conjunction with IEC 612071. For photometric analyzers utilizing tuneable semiconductor laser absorption spectroscopy (TSLAS) for gas measurements, IEC 612077 should also be referred to. This part of IEC 61207 applies to analyzers
