AMS 3186

The trace oxygen analyser AMS 3186 operates on base of an electrochemical sensor. The trace oxygen analyser AMS 3186 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.
