The continuous NDIR industrial photometer can selectively measure concentrations of up to four (4) sample components. The analyzer features gas-filled opto-pneumatic radiation detectors. Detector filling corresponds to the gas being measured, which means that the detector provides optimum sensitivity and high selectivity compared with the other gas components in the sample.

Typical Applications

- Emission monitoring including CO₂ measurement in the same analyzer for emissions
  trading
- Combustion control
- Biofermenters

Sample Components - Smallest Measuring Ranges

- CO	0 - 100 ppm
- CO2	0 - 100 ppm
- NO	0 - 150 ppm
- SO2	0 - 100 ppm
- N2O	0 - 100 ppm
- CH4	0 - 100 ppm
- with stainless steel piping for flammable gas mixtures

Calibration

- Automatic calibration
- Calibration with air and gas-filled calibration cells at the zero/end-point ensures
  plausible measured values
- Calibration cells with proven stability over many years dispense with the need for
  expensive test gas cylinders and reliably adjust the sensitivity
