Oxygen analyser - .PDF file.

Michell Instruments has enhanced its XZR400 range of oxygen analysers, which is ideal for detecting leaks and controlling the purity of gases in heat-treating and environmental control applications.

The oxygen analysers now feature an easy-to-use touch-screen interface to improve operation.

Other highlights include: atmospheric pressure compensation as standard; digital flowmeter for improved readability; user-defined range; two 4-20mA outputs; and RS485 Modbus as standard.

The XZR400TS analyser measures trace oxygen in gases to concentrations as low as 0.01ppm and is ideal for applications such as bottled gas manufacture.

Based on the Metallic Sealed Reference Sensor (MSRS) technology, the instrument detects trace amounts of oxygen very rapidly – within seconds for 90 per cent of a step change.

The metallic sealed reference makes the sensor resistant to pollution and virtually drift-free, reducing the need for calibration and maintenance.

The XZR400TS is highly flexible, with three configurations to choose from.

Rack- or wall-mounted versions are suited to fixed applications either as part of a process or in a laboratory setting, while the portable version allows spot-checks in the field.

Michell Instruments

Michell Instruments is an international leader in high-precision sensing with over 35 years’ experience in the field, specialising in instrumentation for dew point, relative humidity and oxygen analysis. The company serves industries as diverse as petrochemical and pharmaceutical to power generation and food processing. The product range includes:

  • High-precision ceramic moisture sensors to measure trace moisture in process applications.
  • Relative humidity transmitters and sensors for use in HVAC applications, pharmaceutical storage and other production processes where controlled environmental conditions are crucial.
  • Humidity calibration systems and reference dew-point hygrometers enable customers to carry out the calibration of portable hygrometers and relative humidity instruments in-house, saving on downtime and costs.
  • Zirconia and thermo-paramagetic oxygen analysers for combustion optimisation, maintaining gas purity, controlling levels of CO2 in breweries and many other applications.
  • Condumax II Hydrocarbon dew point analysers ensure the quality of natural gas at custody transfer, prevent gas burner failure and the prolong the life of process equipment, helping companies save millions of dollars on repairs and downtime.
  • Trace moisture in hydrocarbon liquids analysers are available in explosion-proof and instrinsically safe versions and allow the continuous measurement of moisture content in a wide range of applications from transformer oil, petrochemical factions and pure hydrocarbons.
  • Process moisture analysers provide continuous on-line measurements of trace moisture in process gases and are available as explosion-proof, instrinsically safe and laboratory versions.

Michell Instruments has three manufacturing locations: Oosterhout, The Netherlands; Lyon, France and Ely, UK. The company has an extensive network of factory-trained application engineers, subsidiaries and distributors stretching across 56 countries.
