Note: When you set the SDA He alongside the SDA O2, it is the replacement unit for the 8000 monitor. They work together to give a similar accuracy as the 8000, and the two combined are the same size as the now obsolete Analox 8000 monitor. The SDA He is fully retrofittable into a panel to replace an existing 8000.


The Analox SDARAAXXA SDA Monitor and Oxygen (O2) Module, Rack Mount, Configured for (O2) 0-100% (Includes MEC O2 Sensor)

The SDA O2 (oxygen) systems comprise of an SDA monitor and an MEC sensor module, including the oxygen cell.

The SDA range is composed of a family of atmospheric analysis systems which are suitable for applications where continuous monitoring of atmospheres is required such as saturation diving and surface supplied diving systems. The SDA range is designed to be highly modular and flexible so that it can be easily integrated into custom atmospheric monitoring solutions. The core of each analyser is a compact monitor unit which provides the display and user interface for the system.

A full colour 3.5 in. TFT display gives clear reading and status information and is suitable for a wide range of lighting and mounting positions. The controls present quick and simple access to the most common system functions such as calibration and alarm adjustment, with more detailed setup and diagnostic information accessed through an easy to use menu system.

The SDA range uses a range of intelligent sensors which means that calibration and change-out intervals can be flagged on screen to assist with your maintenance schedule. The SDA offers a familiar and intuitive user interface and can be easily retrofitted into existing panels and racks or new installations. The RS485 communication ports on the rear of a monitor provide connections to a range of Analox gas and environmental sensors and peripherals.

These provide the flexibility to mount sensors and peripherals alongside the monitor or up to hundreds of metres away without affecting performance.

The SDA range is compliant with the type approval specifications from the major classification societies in the marine industry for both the general power distribution and bridge zones.

Product FAQ's

Ask a Question

  • Is the flow meter panel a new offering? What can I use it for?

    Yes. During the development phase of the SDA, customer feedback suggested a solution for monitoring flow to the O2 analyzers was required. This new flow meter panel now offers this in an easy to install unit which will compliment the analyzers in your panel.
