Open Revolution units were on our stand (301 - 305, with Micropore), working, with CO2 sensors.

We had two units there, one SSUBA and one SSUBA. The SSUBA system was a production unit. Two people on our stand were clients, explaining commercial diving with the system, and another was from the manufacturer explaining that they just made 16 and were pleased when those worked first time. The SSUBA unit was fully injection moulded in Kynar, not a prototype.

We demonstrated the CO2 sensing with the PFD (HUD) and voice annunciation, and also the CO2 reporting to the top console.

The CO2 sensing has been tested in manned underwater tests and in machine tests - the latter go to 1400msw on every unit (twice the physiological limit of a human). It works in air, trimix and heliox. It incorporates a He sensor.
