|381 Series||N/A Portable Tri-Gas Analyzer for H2 / N2 / Air Purging||N/A Thermal conductivity (T/C) cell, electrochemical O2 sensor||N/A 0.1% of gas measured||N/A||N/A For checking purity of hydrogen (H2) in H2-cooled generators and synchronous converters. The Model 381 Series will also monitor the safe purging of H2 during shutdown or startup. This model is designed specifically for generators that are purged with nitrogen (N2) instead of carbon dioxide (CO2).|
|382 Series||N/A Portable Tri Gas Analyzer for Hydrogen Purging with separate O2 channel||N/A Thermal-conductivity (T/C) cell for H2; Electrochemical sensor for O2||N/A 0.1% of gas measured||N/A||
