The Nova 337 Portable Process Analyzer has been designed for the detection of sulfur hexaflouride (SF6) primarily in air or nitrogen (N2). However it can be used in some other applications with several background gases present. Consult Nova on these applications.
The thermal conductivity (T/C) cell provides a fast and accurate measurement of SF6. It has an expected life of over 10 years unless contaminated.
In operation, the sample gas will flow through a built-in regulator or be drawn in by a sample pump draws through the sample tube, filter, flow meter and then on to the T/C cell. The detected SF6 is displayed on an LCD digital meter which has a switchable back light for use in dark areas.
A rechargeable 'gel cell' battery provides enough power for approximately 8 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The recharger is included.
