Sub MkIIIF Hyperbaric Atmosphere Monitor

The Analox Sub MkIIIF is a hyperbaric atmosphere monitoring system capable of measuring oxygen (O2), carbon dioxide (CO2), pressure (depth), temperature and relative humidity.

It is ideal for use in hyperbaric chambers for HBOT or diving and monitoring the atmosphere in Submarine Rescue Vehicles (SRV's).

The Sub MkIIIF can also be configured as an O2 controller to automatically mantain oxygen concentrations to a preset level. The O2 controller would typically be used to maintain the chamber oxygen concentration or the oxygen concentration delivered from a bibs system in an SRV.

The Sub MkIIIF also offers:

  • Real time in chamber information.

  • Simplification of the chamber infrastructure

  • User maintainable operations


Factory configurable, the Sub MkIIIF is able to suit your individual requirements and application. The datasheet provides recommended part numbers for three different applications: medical chambers, SRV's and diving chambers. Should you have any different specifications please contact us with your requirements.
