CO2 Gas Analyzers: For users who demand accuracy, reliability and long term stability

A complete range of CO2 gas analyzers for just about any application.

• EGM-4 Environmental Gas Monitor - For applications that demand portability.
• WMA-4 CO2 Analyzer - For fixed installations requiring long term, continuous measurement and control of CO2.
• SBA-5 CO2 Analyzer - For OEM applications and for customers that require an accurate CO2 sensor.

Our company has been in existence for over 25 years and is considered a leader in CO2 infrared gas analysis measurement instrumentation. Our analyzers are in use in over 100 countries worldwide.  In addition, we offer a range of environmental probes for use with our analyzers enhancing measurement capability.

Important Customer Note

August 15, 2011.  The SBA-4 CO2 Analyzer will slowly be phased out of production in the next 4-6 months as a result of the release of the new SBA-5.  We will do our best to meet all supply requirements during this transition period.  If you have any questions or concerns, please do not hesitate getting in contact with us.

Measurement of CO2 from the Space Needle in Seattle, Washington

On February 15, 2010, NOAA’s Pacific Marine Environmental Laboratory in collaboration with the Pacific Science Center and Seattle’s Space Needle, installed the WMA-4 CO2 Gas Analyzer to measure how much CO2 is in the air over Seattle. There are two air intakes located on the Space Needle. The lower intake is located 300 feet above street level, and the upper intake is located at the very top of the needle. These intakes bring the air through tubes into the shack at the top of the needle. This is where all the science takes place.  To learn more, click on http://www.pmel.noaa.gov/co2/story/Space+Needle and then click on The Method over to the left for more information on where the WMA-4 is deployed for sampling.
