GAS-1031 Carbon Dioxide Analyzer


The GAS-1031 carbon dioxide (CO2) analyzer by Met One Instruments Powered by Acoem uses non-dispersive infrared (IR) gas correlation spectroscopy to provide accurate, stable, and repeatable measurements of gaseous CO2.

It can be configured to operate in absolute or differential mode providing flexibility within the analyzer, making it well suited for ambient CO2 measurements in addition to applications such as dilution extractive stack monitoring.


Based on the GAS-1030 which has the following approvals:
• US EPA approval (RFCA–0509–174)

The Met One range of analyzers have been designed using experience and knowledge gained from operating large air quality monitoring networks for more than 40 years. The result is instruments that integrate seamlessly into continuous monitoring networks.

• Guaranteed performance backed up by a two-year warranty.
• Superior remote instrument control, diagnostic viewing, and calibration minimize on-site maintenance requirements.
• Comprehensive data logging and remote viewing of over 200 operational parameters.
• Versatile interfacing through RS232, USB, analog and digital I/O, TCP/IP, and optional Bluetooth.
• Easier setup through an intuitive menu system with ‘Quick Menu’, advanced GUI, and a large keypad with tactile keys.
• Instant display of operational status using illuminated traffic lights on the front panel.
