Unpacking and Inspection

The user should always inspect the shipping package for damage. If there is damage evident,
please save the package and notify the shipping company immediately.

General Description

The Helium Analyzer is a hand-held device for measuring Helium content in a gas mixture, and
is specifically designed to confirm the Helium content in a gas mixture similar to normal air or
nitrogen. The Analyzer is powered by rechargeable batteries. (Figure 1 shows the top panel.)

Fig. 1. Unit top panel view.

The LCD displays the helium content from 0 to 100% with 0.1% resolution. When the low
battery indicator LED is on, the unit’s battery needs to be recharged prior to use. The patented
sample unit allows the user to flow a gas mixture through the sensor inside the unit, as well as
to seal the gas mixture in the sensor for measurement.

Operation

The operation of the unit is very simple and does not require a flow control regulator. The
operation is as simple as 1, 2, 3.

Step 1. Pull up the sensor cap and flow gas mixture
through the gas inlet with a steady flow for about 10
seconds. (Enough time to clear the line of any existing
gas).

Step 2. Push the sensor cap down firmly to stop the gas
flow and seal the gas mixture inside the device.

Step 3. Turn on the power switch and wait for the display to give a stable reading (less than
one minute), which is the percentage content of helium in the gas mixture tested.

Note: Always turn off the power after you take the reading to extend the battery life.

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.
