Product catalog summary
Overview: The AF22e is an eco-designed ultraviolet fluorescence analyzer for measuring sulfur dioxide (SO2) concentrations in ambient air, compliant with EN 14212 standards. It offers excellent metrological performance, innovative photomultiplier module design, and real-time calibration capabilities.
Features and Benefits:
  • High sensitivity and signal stability due to innovative photomultiplier module.
  • Real-time calibration graph and animated synoptic for operational monitoring.
  • Service assistance with predictive maintenance and step-by-step service guides.
  • Plug & play principle with automatic recognition of electronic boards and devices.
  • Embedded communication protocol for DAS with automatic recognition and configuration.
  • Local and remote control capabilities for configuration, calibration, and diagnostics.
  • Eco-friendly design with ultra-low power consumption and modular concept for robustness and ease of service.
Technical Specifications:
  • Measurement range: 0-1 ppm / 0-10 ppm (user selectable or auto-ranging).
  • Detection limit: <0.3 ppb, Zero noise: <0.2 ppb, Span noise: 0.4% of reading (0.3 ppb minimum).
  • Zero drift: <0.5 ppb / 24h, <0.5 ppb / 7 days; Span drift: <0.5% of F.S over 24h, <0.5% of F.S over 7 days.
  • Response time: < 60s, Repeatability: 0.4% of reading (0.3 ppb minimum), Linearity: 1% of F.S.
  • Sample flow-rate: 20 L/h, Power supply: 100-250 VAC, 50/60Hz, 24VDC (option).
  • Power consumption: 70W at start-up, 30W nominal.
  • Connectivity: Ethernet, USB, serial RS232/RS485 (optional).
  • Optional analog output with external opto-isolated I/O interface.
  • Communication protocols: Modbus, Mod4, UDP, Baeyrn.
  • Dimensions: 483 x 545 x 133 mm, Weight: 9.8 kg.
  • Operating temperature: 5°C to +40°C.
Principle of Operation: The analyzer uses ultraviolet fluorescence to measure SO2 concentrations. SO2 absorbs UV energy and emits fluorescence, which is detected by a photomultiplier tube. This method ensures accurate measurements by eliminating hydrocarbon interferences.
Main Options:
  • Built-in permeation bench with SO2 tube.
  • Internal converter for H2S monitoring and external converter module for TRS compounds.
  • Enhanced temperature range up to +50°C for use without air conditioning.
  • Pressure and temperature compensation, internal solenoid valve block, and internal sampling pump.
  • Built-in web-server for remote emulation of the analyzer.
