Nova 436 Continuous Hydrogen Analyzer - 2

DESCRIPTION The Nova Model 436RMN7 Tri-gas analyzer is designed specifically for monitoring H2 purity in a power generator and to monitor the purging procedure during shut down. The analyzer can measure the following gases by switch selection: Range 1: 0-100.0% H2 in Air; Range 2: 0-100.0% H2 in CO2; Range 3: 0-100.0% Air in CO2. An isolated 4-20 mA recorder output is provided for the range of 85-100% H2 in Air. The Model 436 analyzer is typically divided into 2 sections which are electrically connected. The control section contains the main microprocessor board as well as the digital...
