The Sub MkIIIF has been designed to be a flexible gas monitor. Configured to meet your specific requirements, the REM units allow for variable installation and location of sensors too.

The Sub MkIIIF provides vital gas readings of oxygen (O2), carbon dioxide (CO2), temperature, humidity and pressure allowing it to be used in both hyperbaric and hypobaric situations. The system consists of a central display unit and can be connected to a maximum of 3 remote sensors (REMs).

REMS are:

  • REM 1 measures oxygen (O2), carbon dioxide (CO2), and pressure
  • REM 2 measures temperature and humidity
