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.
