382 SERIES PORTABLE TRI-GAS ANALYZER FOR HYDROGEN / CARBON DIOXIDE / AIR PURGING WITH SEPARATE OXYGEN DISPLAY APPLICATIONS For checking the purity of hydrogen (H2) in H2-cooled generators and synchronous converters, and for monitoring the safe purging of H2 during shutdown or startup. Will also measure oxygen (O2) level inside of generator, including during H2 purity operation. FEATURES • Rugged design, easy to operate, fast warm up and response • Monitors 0-100% H2 in air, H2 in CO2, Air in CO2 by rugged long-life thermal conductivity cell • Long-life electrochemical sensor for separate display of O2 • Digital readout meters with backlight • Rechargeable battery operation • 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 NOVA ANALYTICAL SYSTEMS www.nova-gas.com

DESCRIPTION The Nova Model 382 Tri-Gas Analyzer with separate O2 channel is designed for monitoring the H2 purity inside a power generator and to monitor the purging procedure during a generator shutdown or startup. It can also measure oxygen content in a hydrogen atmosphere. The separate O2 sensor and display remain active regardless of which other range is selected. The analyzer contains a temperature-compensated thermal conductivity (T/C) cell, electrochemical O2 sensor, amplifier board, digital readout, range switch, pressure regulator, gas flow control valve, pump, and a flow indicator....
