JOSHUA F I think it is, it only measures depth and tank pressure.
MARK P Nitrox Compatible to 40% (The Recreational Limits of Nitrox)
COREY M Yes it is nitrox capable.
PAUL B Its not a computer. Its a depth/pressure guage.
CRAIG C These are analog gauges and therefore do not perform any auto-calculations. For any dive using these gauges, you will need to follow the standard dive tables and their recommended bottom times/surface intervals. These gauges will only help you keep track of air pressure in your cylinder and your current/max depth.
HARRY C Yes, this set of gauges is nitrox compatible. I have done numerous dives in the carribean with this set and have had no problems.
NICHOLAS R From the factory it is not O2 clean. Though it does not take much for Mares tech to set it up for Nitrox.
BOB H The pressure gauge is Nitrox compatable.
