AMS 3126 Gas Analyzer

The trace oxygen analyser AMS 3126 has been developed for the measurement of PPM and Vol % concentrations of oxygen traces in gases with combustible components. Two sperate elecrochemical sensors, calibrated for the application, guarantee highly accurate measuring values in both ranges.

The electrochemical sensors in the trace oxygen analyser AMS 3126 are interconnected electronically. This provision ensures to protect the sensor for the PPM concentrations efficiently against high oxygen concentrations. The result is a high availability of the trace oxygen analyser AMS 3126 for process measurements.
