OXYTRANS M - Oxygen (optical; mobile)

OXYTRANS M is a portable , optical measuring instrument for the continuous measurement of dissolved oxygen in liquids and gases . It is designed for applications requiring maximum sensitivity and the highest accuracy – while being easy to use and virtually maintenance-free . Electrolyte solutions are not required, and no oxygen is consumed during measurement.


Application

OXYTRANS M is a portable, optical oxygen sensor for measuring O₂ in:

  • degassed water
  • wort
  • Beer
  • CO₂

Dissolved oxygen has a negative impact on flavor stability and shelf life .


What does the device measure?

  • Oxygen ( O₂ ) in liquids and gases (optical measurement)
  • Temperature compensation of the measurement signal via internal Pt100

Measurement principle (luminescence quenching)

The measurement is based on optical luminescence:

  • The measuring head contains an optical window (glass component) with a thin indicator layer .
  • An LED illuminates the indicator layer with blue-green light .
  • The indicator layer then emits red light, which is detected by the sensor.
  • If O₂ is present, excitation energy is transferred to oxygen molecules – the detected signal decreases with increasing O₂ concentration .
  • Other gases do not affect the measurement result, as they do not absorb this energy.
  • Temperature drifts are automatically compensated via the internal Pt100 .

What makes OXYTRANS M practical

  • Optical technology – no need to change electrolyte and membrane
  • Short response time and excellent long-term stability
  • Suitable for a wide range of concentrations and temperatures
  • Highly accurate and virtually maintenance-free
  • Robust aluminum housing ( IP 65 )
  • Hoses are easy to connect.
