Detail Nova 380 Tri-Gas Analyzer For Hydrogen-Cooled Generators


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.


Rugged design that is easy to operate
• Fast warm up and response
• Monitors 0-100% H2 in air, 0-100% H2 in CO2,
0-100% Air in CO2
• Rugged long life thermal conductivity cell
• Digital readout meter with backlight
• Rechargable battery operation
• Modular layout that is easy to maintain
• Built-in flow meter, flow control valve, and pump
• Built-in pressure regulator prevents over pressuring
of pump and sensor
• Weatherproof (WP) cabinet with clear lexan cover
• Sample pressure ranges 0.5 PSI to 125 PSI


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
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.
