Model 380 Portable Tri Gas Analyzer for H2 Purging

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

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 indicator. 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.

Applications
For checking purity of hydrogen (H2) in H2-cooled generators and synchronous converters. The Model
380 Series will also monitor the safe purging of H2 during shutdown or startup.
