ECHO Solid State is a gas analyzer designed for technical divers who are serious about the quality of their breathing gas. Whether mixing nitrox for a reef dive to trimix for a more ambitious undertaking, ECHO tells you exactly what’s in your cylinder so you can focus on the dive, not on doubts.
Connecting to the Divesoft app via Bluetooth makes the whole blending workflow automatic, from analysis to cylinder labeling in minutes.
ECHO also checks for carbon monoxide in your breathing gas – a type of contamination that’s invisible, odorless, and tasteless, but absolutely necessary to detect before diving. It’s the safety check that’s easy to overlook but impossible to regret.
Helium measurement is handled by an ingenious acoustic sensor that never needs replacing. Less maintenance, one less concern between dives.
Light enough to throw into your dive bag without a second thought and rugged enough to withstand the journey, ECHO is the kind of gear that quietly earns a place on everyone’s equipment list.
