Extractive UV gas analyzer

The multi-functional SIPROCESS UV600

The SIPROCESS UV600 is a specialist in extremely selective NO measurements with small measuring ranges. As an all-round device, it is also suitable for other UV-active gases such as NO2, SO2, and H2S. Thanks to its spectral range, no cross-sensitivities to CO2 and H2O are to be expected. Innovative signal processing and highly stable detectors ensure outstanding long-term stability and compensate for drift and influencing effects. With state-of-the-art electronics and software, the SIPROCESS UV600 has the necessary interfaces for remote monitoring from a network and for connecting to process control systems.

Technical specifications

Max. number of components
UV-active gases, e.g. NO, NO2, SO2, H2S
Smallest measuring range
Component specific: 0–10 / 0–1000 ppmv
19" withdrawable unit (4 HU)

Benefits at a glance:

  • Simultaneous measurement of NO and NO2 with subsequent compilation.
  • NO2 converters or CLD analyzers are therefore not required. This means:
    - Lower maintenance effort (no converter function check)
    - Reduced operating costs because no additional equipment is required, such as an ozone generator and the like 
  • Measurement in the UV range
    - Measurement not effected by H2O and CO2
    - Very low SO2 and NO measuring ranges possible 
  • UV Resonance Absorption Spectrometry (UVRAS)
    - Measurement of very low NO concentrations: Measuring range 10 ppm
    - Very low cross-sensitivity to other gases 
  • Very long service life of the UV light source
  • Low drift and high stability through four-channel measuring method with double quotient calculation
  • True reference measurement for drift-free, stable measurements
  • All modules “temperature controlled,” regardless of ambient temperature fluctuations
  • Optional calibration device
    - Filter wheel with test cells that can be swiveled into the beam path for calibration; no test gases required
    -Calibration: manual or automatic
