TRI-GAS ANALYZER FOR MONITORING
PURITY AND PURGING OF HYDROGEN
COOLED POWER GENERATORS
APPLICATIONS
For continuous analysis of hydrogen (H2) purity and for
purge monitoring of hydrogen-cooled generators and
synchronous converters.

FEATURES
• One analyzer monitors all 3 gases for purity (Range 1) or
purging (Ranges 2 and 3):
• Range 1: 0-100% H2 in Air
• Range 2: 0-100% H2 in CO2
• Range 3: 0-100% Air in CO2
• Bright digital readout
• 4-20 mA isolated output for 85-100% of H2 in Air
• Thermal-conductivity cell with high accuracy and
repeatability, cannot be burned out.
• Explosion-proof gas detector enclosure suitable for
Class 1 Division 1 Group BCD rated areas
• Fast response (T90 -10 to 15 secs)
• Built in pressure regulator

OPTIONS
• Isolated 4-20mA output for any range selected
• 2 levels of low H2 purity alarms & detector fail alarm
• Automatic Calibration by microprocessor control
available on N7MC configuration
• Serial output with data-logging software
• Oil vapor filter assembly
