Contactless and Micro-invasive Oxygen Measurement

Electro-Optical Module EOM-O2-micro

The EOM-O2-micro is a precise single channel OEM solution for measuring oxygen. It comprises micro-optics compatible with 140 µm silica fibers, and can be used for contactless measurements as well as with micro-invasive sensors. The small outer dimensions and low power consumption enable a simple integration of this OEM transmitter into custom monitoring & control systems. A serial communication protocol is offered for data exchange between a PC or another host unit and the EOM-O2-micro.

  • Fast integration with integration package
  • Variety of sensor integrations available
  • Assembled according to ISO 9001
