ECHO is a next-generation scuba gas analyzer designed for divers, blending stations and dive centers.
More Than an Analyzer. Total Control of Your Gas.
Advanced sensors, maximum safety, and a powerful app in one device. From off-grid measurement to precise gas blending, everything you need for confidence below and above the surface.
Gas Analysis
Gas Mixes
ECHO analyzes breathing gas mixes used in diving, including nitrox and trimix.
Gases Measured
Oxygen
Helium
Carbon Monoxide Detection
ECHO detects carbon monoxide contamination in breathing gas mixes.
Carbon monoxide detection adds an additional safety layer when checking gas quality before a dive or verifying gas fills in blending stations.
Interface
Display
Integrated HR-TFT display showing measured values and device status.
App
Models that work with the Divesoft App allow extended data display and management.
GasBlend - advanced Best mix manager, blending tools.
Label printing through any printer connected to the phone.
Practical Use
ECHO is designed for divers, dive centers and gas blending stations.
Typical applications include:
> checking breathing gas mixes before dives
> verifying trimix and nitrox fills
> monitoring gas quality in blending stations
> detecting possible contamination of breathing gas
The compact design makes ECHO suitable for everyday use in demanding diving environments.
Hardware
Sensors / Measurement Principle
Oxygen measurement using an electrochemical oxygen sensor. Helium content is determined using the speed-of-sound measurement principle.
Carbon monoxide detection uses a dedicated CO sensor.
Power
Rechargeable internal battery. Charging via USB-C.
Construction
Durable injection-molded reinforced plastic body.
Integrated TFT-HR display and sealed electronics designed for everyday use in dive centers, blending stations and technical diving environments.
Cylinder Labels
ECHO supports printing gas mixture labels via APP, direct via ECHO coming soon.
Gas cylinder labels can be printed directly after gas analysis using a compatible Zebra label printer connected to the analyzer.
This allows clear identification of analyzed gas mixes for cylinders used in technical diving.

FAQ
Questions about ECHO?
What gases can ECHO analyze?
ECHO measures oxygen and helium content in breathing gases, allowing verification of nitrox and trimix mixes.
Can ECHO detect carbon monoxide?
Yes. ECHO includes a dedicated CO sensor that helps identify carbon monoxide contamination in breathing gases.
What is the difference between the oxygen sensors?
ECHO can be ordered with a traditional galvanic oxygen sensor or a solid-state optical oxygen sensor. The solid-state sensor offers longer lifetime and requires less maintenance.
Can ECHO connect to the Divesoft App?
Yes. Compatible models can connect to the Divesoft App to store gas analysis records, manage cylinders and organize dive information.
Can ECHO print cylinder labels?
Yes. ECHO can generate gas mixture labels when connected to a compatible Zebra label printer.
