AMS 5100 Dewpoint

The basis of the Trace Oxygen Analyser AMS 5100 DP is the development project "AMS 5000" for a compact electronic to be used with Zircon dioxide and electrochemical sensors for the measurement of trace oxygen and Oxygen concentrations in Percent range.

The Trace Oxygen Analyser AMS 5100 DP is suitable for the measurement of oxygen traces in inert gases. For this application the Trace Oxygen Analyser AMS 5100 DP is equipped with a Zircon dioxide sensor. Due to the compact size of the electronics the Trace Oxygen Analyser AMS 5100 DP can be mounted in an electronic housing IP 20, 42 TE, 3 HE and has a depth of 250 mm.

The Trace Oxygen Analyser AMS 5100 DP is available in several housings for General- and Ex-Applications. For determine the dewpoint of the sample gas the analyser coud be equiped with a dewpoint measurement in addition to the oxygen measurement.

AMS 5100

The list of available options includes the following features:

  • electronical/pneumatic gas supply pump
  • electronical flowmeter
  • auto calibration
  • pressure reducer
  • particle filter 2–7µm
  • different housings
