AMS 5100 Z

The basics of the Oxygen Analyser AMS 5100 Z is the development project "AMS 5000". The Trace Oxygen Analyser AMS 5100 Z is designed for the measurement of the lowest Oxygen traces under presence of oxidable components for example in Air separation plants. For this application the Oxygen Analyser AMS 5100 Z is equipped with a catalytic inactive Zircondioxid sensor. Due to the compact design the Oxygen Analyser AMS 5100 Z is available in different housing types.

A long list of options allows to adopt the Oxygen Analyser AMS 5100 Z for almost every application. The software for remote control and remote service with access via the customer computer network further increase the flexibility of the Oxygen Analyser AMS 5100 Z in an application.

Oxygen measurement

Please note: The cross interference from combustible gases to the Oxygen measurement depends upon the temperature, the gas flow rate and both the concentration of Oxygen and of the combustible component.
