DiveSoft ECHO Analyzer Solid State Sensor

ECHO analyzer is a high-precision instrument built for real-time measurement of O₂ (0–100%, 0.1% resolution), He (0–100%, acoustic speed-of-sound method), and CO.  ECHO supports both galvanic and maintenance-free solid-state oxygen sensors.

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. 

A high-reflective TFT display ensures clear readability even in bright environments.

It runs on a rechargeable Li-ion battery with up to 100 hours of operation and charges via USB-C. Bluetooth LE connectivity and integration into DivesoftApp  enable gas label printing and stellar gas blending workflows!

The device maintains a compact, field-ready form factor: 127 mm diameter, 37.5 mm thickness, and 288 g total weight. Including the integrated wrist strap, total length is 410 mm, allowing for practical handling in both field and lab conditions.
