Frequently asked questions
Why do I need a Trimix analyser?
If you dive with Trimix, you need to know the helium content of the mix as well as the oxygen. The SOLO measures both.
Do I have to replace the helium sensor?
No. Helium is measured via the speed of sound, so there is no helium sensor to replace. The electrochemical oxygen sensors have a 12-month warranty.
What does the “FOUL AIR” warning mean?
The SOLO uses it to warn of hypoxic mixes, meaning mixes with too little oxygen.
How do I charge the analyser?
Via the USB-C port. A full charge takes less than 4 hours. The USB charging cable is included.
