The SDA range was designed for gas detection with commercial diving in mind. The SDA O2 monitor provides reliable oxygen monitoring with readings taken from a fast response, accurate, long life electrochemical sensor.

The SDA O2 monitor provides a full-colour display of the oxygen reading taken from an electrochemical sensor. The alarm set points and calibration can be achieved using the front panel user interface and the SDA O2 provides audio/visual alarms, optional data-logging and 4-20mA/relay outputs. The monitor interfaces with our state of the art digital MEC sensor.


The SDA O2 oxygen monitor replaces the now obsolete Analox 1000 and is fully retrofittable as a direct replacement.


Maintaining a comfortable and safe chamber environment is vital to achieving a successful diving operation. The accuracies supplied by the SDA O2 are compliant with DNV, IMCA, Lloyds, ABS, and ADCi requirements/guidelines.


The SDA O2 is normally located in sat/dive control and the sensors can be either located at the panel or inside the chamber or diving bell.


We offer an optional flow panel to go alongside the SDA O2 which provides fine control after the sample has been reduced from the chamber. Both the SDA O2 and the option flow panel can be provided as either rack or panel mount.
