The thermal conductivity (T/C) cell provides a fast and accurate measurement of He. It has an expected life of over 10 years unless contaminated.
In operation, a built in sample pump draws in the gas sample through the probe, filters, flow meter, and on to the T/C cell. The detected He is displayed on a digital readout meter.
A rechargeable battery provides power for approximately 8 hours of operation and the analyzer can be used while it is being recharged. The recharger is included.
