7900 SERIES
SINGLE & MULTI-GAS INDUSTRIAL
PROCESS GAS ANALYZERS

APPLICATIONS
For continuous monitoring of any combination of gases such as
oxygen (O2), methane (CH4), carbon dioxide (CO2), carbon
monoxide (CO), and hydrogen (H2) for industrial processes
including heat treating atmospheres.

FEATURES
• Sensitive infra-red detectors for CO, CO2, and CH4
• Thermal conductivity detector for H2
• Long life (4-5 years) electrochemical oxygen sensor;
both PPM and % ranges available
• Sensors/detectors temperature-controlled or
compensated for maximum stability
• Bright digital display for each gas
• Built-in sample pump or pressure regulator
• Easy to maintain modular layout

OPTIONS
• Dielectric ceramic sensor for standard or
low range dew point
• Hi/Low gas, low flow, and diagnostic alarms available
• Isolated analog, RS232, RS485, MODBUS®, and Ethernet
outputs available
• Sample conditioning systems available for removal of
moisture, acidic gas, and dust
• Cabinet purge system available for use in hazardous areas
• Automatic calibration with touch screen LCD display
• Cabinet coolers / heaters can be fitted to most models
• Heated filters and high temperature probes
