- For NO, NO2, SO2: Very low cross-sensitivity with other gases
- All modules are thermostatically-controlled, and thus independent of the ambient temperature
- Simultaneous measurement of NO and NO2 with subsequent calculation of total. Therefore neither an NO2 converter nor a CLD analyzer is required.
- Measurement in the UV range:
- No cross-sensitivity with H2O and CO2
- Very low SO2 and NO measuring ranges possible
- UV resonance absorption spectrometry:
- Measurement of very low NO concentrations
- Very low cross-sensitivity possible
- Very long service life of UV lamp (usually 2 years)
- Low drifts and high stability thanks to four-channel measuring method with double generation of quotient
- True reference measurement for low-drift, stable results
- Interface for remote monitoring in networks and linking to process control systems
- Optional calibration unit
- Filter wheel with calibration cells which can be automatically swung into the optical path
- Low consumption of calibration gas
- Manual or automatic calibration possible
