AMS 3110 Ex

The portable oxygen analyser AMS 3110 is the ideal instrument for discontinuous measurement of PPM or Vol. % of oxygen concentrations in Ex classified areas. The AMS 3110 is equipped with an electrochemical sensor and contains both flow regulation and control appliances. The connection to the process gas pipe is by quick-connect coupling. The gas flow within the AMS 3110 can be controlled by a mechanical flowmeter conveniently located on the instrument front. The AMS 3110 can handle up to 10 bar (abs.) of gas pressure at the process gas inlet.

The potted lead-acid rechargeable battery provides up to 8 hours continuous power.

The Oxygen Analyser AMS 3110 is certified for applications in Ex-zone 2 according to ATEX II 3G.
