Item # 380 Series, Portable Tri Gas Analyzer for Hydrogen Purging


The Nova 380 Series Tri-Gas Analyzer is designed for monitoring H2 purity inside a power generator and to monitor the purging procedure during a generator shut down or start up.

The analyzer contains a temperature compensated thermal conductivity (T/C) cell, amplifier board, digital readout, range switch, pressure regulator, gas flow control valve, pump and a flow indictor. A recorder output is optional.

The T/C cell does not burn the sample nor is it consumed in any way, so it has a life expectancy of over 10 years. Measurement results are fast and accurate. A rechargeable 'gel cell' battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged.
