As long as the kinds of composing gases are known, the mixture ratio (concentration) can be determined by measuring the reflection ratio. The optic interferometer applied in the CV Pro™ displays “Interference Stripes” on the CCD. The Interference Stripes move proportional to the reflection ratio. The amount of the movement is measured by the solution of the interference stripes on CCD with Fourier analysis, and the result is converted to the reflection ratio. Concentration can be displayed by adding data like “measuring gas” and “base gas” to the reflection ratio determined by high accuracy. Sensitivity of the optic interferometer depends on the length of the chamber. Since the length of the chamber is physically unchanged by elapsing time, the high accuracy is maintained. 3RKI.D.BR.0001_A Overview of Operation Sample System In The Portable Case Easy access to operate with the sample system already in the case.

Typically the factory calibration of the CV PRO™ will be calibrated to meet the ±0.1 MJ/Nm3 (2.7 BTU/cf) accuracy statement.
