• Version with IR detector with chopper compartment purging:
This version consumes approx. 100 ml/min of purging gas; you must set an inlet pressure of
300 kPa (3 bar).
• Version with UV absorption photometer for small SO
measurements
Benefits
• AUTOCAL can be carried out with ambient air (zero-point calibration for the IR and UV
components and full-scale calibration as well as calibration point for oxygen sensors) and is
therefore highly cost effective as no calibration gases and accessories are required
• Monitoring of the flow rate using a pressure switch, alarm when the flow rate falls below the
nominal flow rate
• High selectivity thanks to multi-layer IR detectors,
low cross-sensitivity to water vapor
• Sample chambers can be cleaned (for analysis chamber lengths of 20mm and more),
resulting in cost savings through reuse following contamination
• Menu-assisted operation in plain text, thus high operational safety
• Service information and logbook, cost savings through preventive maintenance and help for
service and maintenance personnel
• Increased safety through coded operator levels, thus protection against unauthorized access
or clumsy working
• Open interface architecture (ELAN (RS485), PROFIBUS-DP/PA), thus simplified process
integration
• Communication software. SIMATIC PDM and SIPROM GA.
• Remote operation and control (via SIPROM GA and PROFIBUS).
Special benefits when used in biogas plants
• Continuous measurement of all 4 important components, including H
• Long service life of the H
no diluting or backflushing necessary
