Oxygen analyzer Smart O2

monitoringprocessfor environmental assessments

The Smart O2 is a compact zirconia oxygen analyzer for continuous online measurement of O2 in industrial processes. It is built for operators who need a dependable oxygen reading at low running cost: the zirconium oxide sensor is long-term stable and needs little calibration.
Typical applications:

• Chemical and pharmaceutical industry
• Food industry
• Biogas plants
• Air quality monitoring
• Recycling and environmental technology

What operators get:

• Ready to measure 60 seconds after switching on
• Up to 4 measuring points with one analyzer
• Compact housing of 310 × 133 × 221 mm with touch display and 4 status LEDs
• Internal sample pump, so the unit draws the sample gas itself
• Digital inputs, relay outputs and RS232 as standard; Profibus DP, Modbus TCP, EtherNet/IP, Profinet and up to 8 analog 4–20 mA outputs as options

The Smart O2 is designed for non-explosive gas mixtures free of silicone compounds, fluorinated hydrocarbons, sulfur oxides and hydrogen.
