Gas Analysis
Gas Mixes
ECHO analyzes breathing gas mixes used in diving, including nitrox and trimix.
Gases Measured
Gas mixture, oxygen, helium, and carbon monoxide
Interface
Display
Integrated TFT-HR 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.
Details Matter.
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.
The analyzer comes with the following:
- Analyzer ECHO
- DVO2 oxygen sensor
- DVO2 connector cable
- USB-C cable
- EVA case
- Professional flow limiter Mk2 DIN G5/8
- connection hose
