AMS 3220 oxygen analyser for vol. % measurement

The oxygen analyser AMS 3220 is designed for the measurement of oxygen concentrations in noble gases and process gases without combustible impurities. For this application the oxygen analyser AMS 3220 is equipped with a zircondioxid sensor. Due to the compact design the oxygen analyser AMS 3220 fits in an electronic housing IP20, 28 TE, 3 HE with a depth of 250 mm.

The oxygen analyser AMS 3220 is available in different housings for general applications and classified areas. The oxygen analyser AMS 3220 is certified by the German TÜV according to European and German environmental regulations and fulfils the requirements for QAL 1 according EN 14181 and EN ISO 14956. The oxygen analyser AMS 3220 is tested for suitable flue gas applications according to TALuft, 13. und 17. BImSchV.
