Operation:
The procedure is simple:
1. Connect the top hose connector marked with a (IN) to the incoming gas supply.
2. Connect the lower hose connector marked with an (OUT) below it to either your
oxygen monitor or exhaust it to a vent.
3. Turn on the power switch (up) and wait about 10 seconds to take your first reading.
Your gas flow should be between 100 cc/min to 300 cc/min for accurate readings.
The unit will read continuously during the flow.
4. The system will operate for about 2 hours on batteries alone or if you plug in the
charger the unit will operate for 5 hours before you need to recharge the batteries.
Cautions
1. The Helium Analyzer is a vibration sensitive device. Please avoid mechanical shock while
handling. Dropping the unit on a hard floor may cause damage to the unit.
2. When operating the Helium unit out doors, please avoid direct sunlight on the unit.
Operating Principle
The Analyzer measures the helium content based on the extreme high thermal conductivity of
helium gas. The unit consists of two main components: one is the sensor block and the other
is the electronic circuit. The patented design allows the unknown gas mixture to flow through
the sensing chamber. Once the gas mixture is inside the sensing chamber, the electronic
circuit then measures the difference of the thermal conductivity between the gas mixture and
the reference gas. The helium content is then calculated by the circuit and displayed.
