Oxygen analyzer GA210 O2

monitoringprocessfor environmental assessments

The GA210 O2 paramagnetic is a paramagnetic oxygen analyzer for continuous online measurement of O2 in process gases, for example to monitor the inerting of explosive gas mixtures in refrigerator recycling. The paramagnetic measuring cell keeps cross-interference from other gas components low and responds quickly.
Typical applications:

• Inerting monitoring, e.g. in the recycling of refrigerators
• Oxygen monitoring in chemical and pharmaceutical processes
• Recycling and environmental technology
• Process and quality control wherever the O2 level decides on safety or product quality

What operators get:

• Three measuring ranges up to 0–100 vol.% O2 with 0.1 vol.% resolution
• Low zero drift: less than ±0.1 vol.% O2 per week
• Up to 6 sample inlets plus 2 separate calibration inlets for nitrogen and oxygen
• Constant pre-pressure set internally; the cell is fed via a bypass at 100 ml/min
• Ready to measure 5 minutes after switching on
• RS232 as standard; Profibus DP, Modbus TCP, EtherNet/IP, Profinet and up to 8 isolated 4–20 mA outputs as options

The analyzer is designed for dried sample gas. Plan a sample gas cooler or another drying stage upstream.
