The helium analyzer has a solid aluminum alloy that guarantees stability. It is therefore extremely resistant and protected against mechanical damage. The surface is also anodized to protect it from scratches.
On the top, the analyzer has a membrane keyboard and an OLED display on which the measured values are displayed. The gas to be measured is fed through the inlet (analyzed-gas-inlet) on the top of the analyzer and passes through the helium concentration to the sensor. From there it enters the oxygen sensor block and the air (Exhaust). The flow rate of the mix to be analyzed is 0.2l/min.
The He/O2 analyzer is equipped with a standard nine-volt battery (type 6F22) or can be powered by an external power supply (12V adapter DC) (left side / power supply connector).
The battery is accessible from below. To do this, loosen two screws of the cover. On the top of the He / O2 analyzer is an interface (connector for attaching) for attaching tools (for measuring pressure, bottle temperature, electrical voltage, etc.). A USB port is located on the left side (USB connector) and is used to transfer data to a computer and to update the firmware.
