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.
3. The reading should be taken one minute after turning on the power switch. The power
should be turned off after taking the reading.
4. When the unit is not used, always pull up the sensor cap to allow the sensor chamber to be
exposed to ambient air.
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 sensor block and the other is
the electronic circuit. The patented design allows the unknown gas mixture to flow through the
sensing chamber and seal it inside for measurement. Once the gas mixture is sealed 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.
