Siemens Siprocess - Model UV600 -Extractive UV Gas Analyzers

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.

• 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

• Max. number of components: 3
• Components: UV-active gases, e.g. NO, NO2, SO2, H2S
• Smallest measuring range: Component specific: 0–10 / 0–1000 ppmv
• Housing: 19" withdrawable unit (4 HU)
