Portable tri-gas analyser for oxygen, helium and carbon monoxide
The Divesoft ECHO is a portable gas analyser measuring oxygen, helium and carbon monoxide in one handheld unit.
The Divesoft ECHO is a compact portable gas analyser designed for divers and blending stations that need to verify breathing gas mixtures before diving. It measures oxygen, helium and carbon monoxide in one handheld unit, making it suitable for nitrox, trimix and general breathing gas safety checks.
Oxygen and helium are measured from 0 to 100 percent with 0.1 percent resolution and an approximate five-second response time. Helium measurement uses an acoustic speed-of-sound sensor, avoiding the need for a replaceable helium sensor. Carbon monoxide is measured from 0 to 100 ppm, with an alarm threshold at 5 ppm.
The analyser connects to the Divesoft app via Bluetooth, supporting a workflow from gas analysis to cylinder labelling and record keeping. The unit includes a high-reflective TFT display for bright environments, a rechargeable battery offering up to 100 hours of operation, and USB-C charging with an approximate 2.5-hour charge time.
At 288 g including strap, the ECHO is portable enough for travel and expedition use. It is supplied with an oxygen sensor, USB-C cable and EVA case. The device is aimed at technical divers, instructors, dive centres and gas blenders who need a compact analyser for routine verification of oxygen, helium and carbon monoxide.
