Flame Ionization Analyzer Model 521

The Model 521 relies on the the flame ionization principle of hydrocarbon gas measurement and features a highly sensitive detector and extremely wide dynamic range.

 

This analog electronic, ambient level hydrocarbon monitor features high sensitivity, fast response, excellent stability, wide dynamic range and low maintenance.
A large digital LCD provides a clear display of total hydrocarbon concentration measurement. Analog gauges are provided for hydrogen fuel, air and sample gas pressure monitoring. A flowmeter is provided on the front panel to monitor bypass sample gas flow. The unit features 19" rack mounting at 5RU height and a typical configured weight of 45 Lb.
