NOVA ANALYT

DESCRIPTION The Nova 337 Portable Process Analyzer has been designed for the detection of sulpur 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 through the sample tube, filter, flow meter and then on to the T/C cell. The...
