Make sure you analyse every tank before use with the DiveSoft analyser. They are highly accurate and reliable and wont need to be upgraded as your diving journey develops.

The analyser is manufactured from high-strength aluminum alloy, which guarantees stable dimensions and resistance against mechanical damage. The surface is hard-anodized to protect it against scratching.

The analyser features a membrane keypad and an easy to read amber OLED display on which the measured values are shown. The gas composition is displayed after approximately 5–10 seconds depending on cylinder pressure.

Measured gas is fed into the analysed-mix inlet on the back of the analyzer and passes through the helium-concentration sensor. From there, it enters the oxygen-sensor block and is expelled into the air by the mix exhaust. The rated flow of the analysed mix is 0.2 L/min.

The analyser is powered by a standard nine-volt battery (type 6F22) (rechargeable Li-Ion supplied) or by an external power supply connected to the left side. The battery is accessible from the bottom by removing the two screws of the retaining cover.

On the back of the analyser, there is a connector for attaching auxiliary devices (for measuring cylinder pressure during filling, tank temperature, electrical voltage and resistance, etc). A USB connector is located on the side for transferring data to a computer and for updating firmware.

The analyser is equipped with a barometric pressure sensor for automatic ambient pressure calibration.
