Item # Model 375K, Portable Flue Gas Analyzer for Oxygen, Carbon Monoxide and Carbon Dioxide, Suitcase (K) Enclosure

The Nova 375 Series Portable Flue Gas Analyzers have been designed for accuracy, reliability, ease of use and ease of service, providing a detailed analysis of flue gas composition. The sensors respond quickly to oxygen, CO2, and CO present in the flue gas sample. The O2 and CO sensor life expectancy is between 3 and 4 years. The CO2 infrared detector life is infinite under normal conditions of use, unless contaminated. The O2 and CO sensors are customer-replaceable. The infrared CO2 detector should not need to be replaced.

In operation, a built-in sample pump draws in the flue gas sample through the S.S. probe, 12 ft. (4 m) sample hose, condensate removal filter, secondary filter and flow meter and then on to the three sensors. The detected O2, CO2 and CO are displayed on a digital meter.

The Nova 375T version also indicates stack temperature for doing fuel efficiency calculations. The temperature sensor is built into the sampling probe. Efficiency charts for each fuel are provided.

A rechargeable battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged. The recharger is included.

Unique Applications
    The 375 Series should not be used for detecting these gases in ambient atmospheres for personnel safety purposes. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific to your needs.
