The trace oxygen analyser AMS 3186 DP operates on base of an electrochemical sensor. The trace oxygen analyser AMS 3186 DP is a micro-processor controlled analyser for the highly accurate measurement of lowest oxygen traces.
Changes in concentrations of < 0,1 ppm of oxygen with a resolution of 0,01 ppm can be measured. The available housings are designed for use in general applications. The lowest oxygen measuring range is 0 … 1 ppm. To determine the dewpoint of the sample gas, the analyser has be equipped with a dewpoint measuring system in addition to the oxygen measurement.
