  • Page 8: Preface

    The Microx 4 & Microx 4 trace are compact, portable, completely stand-alone fiber optic oxygen transmitters. The data management and export is PC supported. The Microx 4 & Microx 4 trace are developed especially for small fiber optic oxygen sensors, oxygen microsensors, flow-through cells and non-invasive sensors. They are based on a novel technology, which creates very stable, internally referenced measured values.

  • Page 9: Safety Notes

    PreSens is explicitly not liable for direct or indirect losses caused by the application of these measurement systems. In particular it has to be considered that malfunctions can occur due to the naturally limited lifetime of the sensor depending on the respective application.
