Item # Model 334K, Portable Process Analyzer for Helium, Suitcase (K) Enclosure


The Nova 334 Portable He Analyzer has been designed for the detection of He primarily in air or nitrogen.

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.
