Description of the analyzer
3. Description of the analyzer
The analyzer 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.
On the front side, the analyzer features a membrane keypad and an OLED display on
which the measured values are shown.
Measured gas is fed into the analyzed-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 analyzed mix is 0.2 L/min
The analyzer is powered by a standard nine-volt battery (type 6F22) 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 analyzer, there is a connector for attaching auxiliary devices (for mea-
suring pressure, tank temperature, electrical voltage, etc.). A USB connector is located on the
side for transferring data to a computer and for updating firmware.
