ECHO is a gas analyzer built for technical divers who take their breathing gas seriously. Whether you're blending nitrox for a deep reef dive or mixing trimix for something more ambitious, ECHO tells you exactly what's in your cylinder, so you can focus on the dive, not the doubt.
Connect it to the Divesoft App via Bluetooth and your whole blending workflow just clicks into place, from analysis to labeled cylinder in minutes.
ECHO also checks for carbon monoxide in your breathing gas, the kind of contamination you can't see, smell, or taste, but absolutely need to know about before you descend. It's the safety check that's easy to skip and impossible to regret doing.
The helium measurement is handled by a clever acoustic sensor that never needs replacing. Less maintenance, one less thing to worry about between trips.
Light enough to toss in your dive bag without a second thought, and tough enough to survive the journey, ECHO is the kind of gear that quietly earns its place on every packing list.
Build time: Due to high demand, Divesoft build time is estimated at 10 working days.
Oxygen sensor
- Electrochemical: ships with the Divesoft 22S electrochemical oxygen sensor. The built-in battery and oxygen sensor carry a 12-month warranty, with up to 100 hours of operation per charge.
- Solid State: ships with the maintenance-free DVO2 solid-state oxygen sensor and connector cable. The solid-state sensor carries a 24-month warranty, with up to 50 hours of operation per charge.
Configuration
- Analyzer Only: the ECHO analyzer and everything needed to start measuring.
- Set with Flow Limiter: adds the Professional Flow Limiter Mk2 (DIN G5/8) and connection hose for controlled, repeatable sampling straight from the cylinder valve.
