SIPROCESS UV600 is an extractive UV gas analyzer that can 
simultaneously measure up to three components. It is a specialist for extremely selective NO measurement with small measuring ranges and an allrounder also for other UV-active gases, e.g. NO2, SO2 and H2S. Due to spectral range no cross-sensitivities to CO2 and H2O are to be expected. 
Innovative signal processing as well as highly stable detectors provide excellent long-term stability and compensation 
of drifts and influencing effects. 
SIPROCESS UV600 with state of-the-art electronics and software has the interfaces required for remote monitoring from a network as well as to the connection to process control systems.

Simultaneous measurement of NO and NO2 with subsequent compilation. NO2 converters or CLD analyzers are thus not required. Therefore:

  • Lower maintenance effort (no converter function check)
  • Reduced operating costs because no additional equipment required, e.g. ozone generator, 

Measurement in the UV range

  • Measurement not affected 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 UV lamp

Low drifts and high stability by

  • four-channel measuring method and double quotient calculation

True reference measurement for drift-free, stable measurement

All modules “temperature controlled”; thereby independent of ambient temperature fluctuations

Optional adjustment device

  • Filter wheel with test cells which are swiveled into the optical path for calibration; no test gases are required
  • Adjustment: manual or automatic
