380 SERIES PORTABLE TRI-GAS ANALYZER FOR HYDROGEN/CARBON DIOXIDE/AIR PURGING 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. FEATURES • 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 • Suitcase cabinet has carry handle and is weatherproof when closed • Sample pressure ranges 0.5 PSI to 125 PSI CALIBRATION • Range 1: Air for Zero, 100% H2 for Span • Range 2: 100% CO2 for Zero, 100% H2 for Span • Range 3: 100% CO2 for Zero, Air for Span NOVA ANALYTICAL SYSTEMS www.nova-gas.com

DESCRIPTION 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.
