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, a built in sample pump draws in the gas sample through the probe, filters, flow meter, and 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.
