SST Sensing – zirconia oxygen sensors

We would like to inform you about new products in Maritex offer – zirconia oxygen sensors from SST Sensing . SST is an European company with over 15 years of experience in gas sensing market. Their offer includes zirconia (ZrO2) sensors, interface boards and detectors for many different applications.

Zirconia oxygen sensors from SST are using innovative, unique closed loop measurement system. While the sensor continuously measure the oxygen level, a heartbeat signal is generated providing an immediate warning of any failures.

The sensing technology and stainless steel construction allow zirconia oxygen sensors to be used in environments where extreme pressure, temperature and high humidity are present.

Depending on your preferences you can select between ready solutions:

and components: zirconia oxygen sensors and interface boards. To meet your requirements SST offers many personalization options:

  • Dimensions
  • Housing styles (flange, screw fit)
  • Cable length (15cm up to 1,1m)
  • Measurement range (25%,100%)
  • Working temperature (-100…250°C, -100…400°C)
  • Output signal (4…20mA, 0…10V, RS-232, RS-485)

Most popular zirconia oxygen sensors applications are:

  • Controlled atmosphere during transport and storage of fruits and vegetables
  • Industry: fumes monitoring, burning process control, chemical process control
  • Aviation, Marine: keep atmosphere in tanks and storage places within non-explosive limits


Additionally, SST Sensing offers optical oxygen sensors using luminescence-based technology. LuminOx O2 sensors provide significant benefits over electrochemical sensors due to their insensitivity to environmental factors such as pressure and temperature.
Main advantages over electrochemical and galvanic sensors are:

  • Long lifetime: over 5 years
  • Wide working temperature range: -30°C – 60°C
  • Factory calibration
  • Digital UART output
  • Measurement range: 0-25% O2
  • Low power consumption
  • 100% ROHS conformity

LuminOx sensors are available in three housing types:: diffusion type, diffusion type with sealed base and flow-through with sealed base.

Full SST Sensing offer is available in our on-line shop .
