Divesoft ECHO Analyser Set w/Flow Limiter

The Divesoft ECHO Analyser is a gas analyser built for technical divers who take their breathing gas seriously. Whether you’re blending nitrox for a deep 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.

Designed for divers, dive centres and gas blending stations, ECHO gives you total control over your gas mixture by precisely analysing oxygen and helium, with integrated Carbon Monoxide monitoring. This set comes in its EVA case, with Divesoft's professional Flow Limiter, connection hose, 22S Oxygen sensor and USB-C cable - ready to be used out of the box.

Connect it to the Divesoft App via Bluetooth and your whole dive preparation or blending workflow just clicks into place, from analysis to labelled cylinder in minutes.

And, as with the Divesoft Solo Trimix and He O2 mixed gas analysers, you'll never have to buy a Helium sensor, as it uses Divesoft's patented method of measuring helium content based on the speed of sound.  

The compact design and its HR-TFT display make ECHO suitable for no-hassle everyday use in demanding diving environments.

Other than essential CO monitoring and Bluetooth connection instead of USB, you'll clearly see ECHO's difference from the lightweight Solo and the more robust He O2 rectangular-shaped analysers: A user- and travel-friendly, compact, round-profile form factor 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. 

Divesoft Echo Portable Diving Gas Analyser

Divesoft ECHO Key Features:

  • 3-in-1 Gas Analysis: Measures Oxygen (O2), Helium (He), and Carbon Monoxide (CO) simultaneously in a single lightweight unit.

  • Integrated Carbon Monoxide Safety: A dedicated internal CO sensor detects contamination from 0 to 100 ppm, with an audible/visual safety alarm set at 5 ppm.

  • Maintenance-Free Acoustic Helium Sensor: Speed-of-sound acoustic technology measures helium content without consumable components, eliminating the need for helium sensor replacement.

  • Standard Electrochemical Oxygen Measurement: Powered by a reliable Divesoft 22S electrochemical O2 cell providing fast, accurate 0–100% oxygen readings (T90 response time ~5s).

  • Bluetooth App Integration: Bluetooth Low Energy (BLE) pairs directly with the Divesoft App (iOS & Android) to log gas mixes, compute blending calculations, and print cylinder labels.

  • Extended Battery Life: Built-in rechargeable lithium-ion battery delivers up to 100 hours of continuous operation on a single USB-C charge.

  • Sunlight-Readable HR-TFT Screen: High-reflective colour display optimised for high visibility outdoors, on dive boats, and in bright environments.

  • Compact & Rugged Ergonomics: Tough PC-ABS housing with an integrated wrist strap, weighing just 288 g for easy dive-bag transport.

  • Complete Professional Kit: Package includes the ECHO analyser, professional Mk2 DIN G5/8 flow limiter, connection hose, USB-C charging cable, and a protective EVA storage case.

Product FAQs

What is the difference between the Divesoft ECHO and Solid State ECHO Analysers?
The Standard ECHO Analyser uses a traditional electrochemical oxygen sensor (Divesoft 22S). Electrochemical sensors are consumable items; they deplete over time when exposed to oxygen and typically need to be replaced every 1–2 years.

The Solid State ECHO Analyser uses a solid-state oxygen sensor (optical/luminescence technology). Solid-state sensors do not use consumable chemicals, meaning they do not deplete over time in the same way. They boast a much longer lifespan and eliminate the ongoing cost and hassle of replacing oxygen cells.

Price: Because of the nature and cost of its oxygen sensor, the Solid State ECHO could be considerably more expensive for you even when compared to changing the Divesoft 22S sensor every 1.5 to 2 years.

Battery Life: It's worth noting that because solid-state sensors typically rely on an active light/optical array to measure gas concentrations, they draw more power than passive electrochemical sensors. Or in practical terms, a runtime of about half that of the standard Echo on a single charge.
How does the Divesoft ECHO Analyser measure Carbon Monoxide?
Both versions of the Divesoft ECHO Analyser (Standard and Solid State) measure carbon monoxide (CO) using the same internal technology: a dedicated electrochemical carbon monoxide sensor.

While the primary difference between the two models lies in how they measure oxygen (galvanic vs solid-state optical), their method for measuring carbon monoxide is identical.

They use a dedicated, consumable electrochemical CO sensor that reacts with carbon monoxide to produce an electrical current proportional to its concentration.

The sensor detects CO concentrations from 0 to 100 parts per million (ppm) and alerts if CO concentration exceeds 5 ppm.

Life Span: Electrochemical CO sensors have a finite operational lifetime, regardless of use. The factory-installed sensor has a manufacturer-rated lifetime of 2 years from the date of manufacture.

The sensor must be replaced regardless of apparent function once the rated service life has elapsed. An aged sensor may continue to produce readings while having significantly reduced sensitivity, potentially failing to alarm at dangerous concentrations.

Calibration: Divesoft recommends performing a "zero calibration" for the CO sensor every 2–6 months in clean air (outdoors or in a well-ventilated room). They also outline a "bump test" procedure in which you expose the sensor to a known bump gas (10–50 ppm CO) to ensure the sensor responds and triggers the alarm correctly.
How does the Divesoft ECHO Analyser measure Helium?
Similar to other Divesoft mixed-gas analysers, such as the Solo Trimix and the He O2, the Divesoft ECHO Analyser measures helium using the acoustic speed-of-sound principle.

Instead of using a chemical reaction, the device calculates the concentration of helium by measuring how fast sound waves travel through the breathing gas mixture.

Because acoustic speed-of-sound technology relies entirely on physics rather than a chemical reaction, the Echo’s helium sensor has no consumable parts, never degrades over time, and never needs replacement. However, because the calculation relies on the oxygen reading, your O2 sensor must be properly calibrated for the helium reading to remain accurate.
What other mixed gas analysers does Divesoft do?
Divesoft also provides the Divesoft Solo Trimix Analyser and the Divesoft He O2 Analyser.
What is the manufacturer warranty for the ECHO Analyser sets?
Standard ECHO: The analyser unit has a 24-month warranty, but the built-in battery and electrochemical oxygen sensor are covered by a 12-month warranty.

Solid State ECHO: Both the analyser unit and the solid-state oxygen sensor are covered by a full 24-month warranty.
Are there any other considerations?
• One cannot claim that even the solid-state ECHO promises “Zero maintenance”. The solid-state O₂ sensor still requires periodic calibration, while standard O2 cells will need to be replaced more periodically depending on use and deterioration.
• In both the standard and solid-state sets, it needs to be noted that the ECHO’s CO sensor has a finite life and must eventually be replaced by an authorised service centre.
• Label printing is handled through the Divesoft App. The app generates a PDF that can be sent through the phone’s printing workflow; as of this listing, the ECHO does not currently print directly to a Zebra printer.
• The optional professional flow limiter matters: Divesoft recommends an external limiter for all helium-containing mixes. The ECHO “Set” includes this Professional Flow Limiter Mk2 and its connecting hose, which need to be taken into account when comparing prices.
