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.

Halcyon has introduced the Symbios TriSense, a compact handheld gas analyser designed to measure oxygen, helium and carbon monoxide in breathing gas mixtures. The unit was shown publicly at both the DEMA Show and boot Düsseldorf, where it attracted attention for its small form factor and solid construction. According to Halcyon, availability is expected in late spring or early summer 2026.

The versatile device can be paired with an array of sensors for varied applications, including the continuous monitoring of ambient gases, hyperbaric chambers, rebreathers, air quality, and more

Standard configurations include oxygen, carbon dioxide, carbon monoxide, humidity and VOCs (volatile organic compounds). It is possible to connect the instrument to many other sensors and to change the configuration of the sensors and instruments.
