The Nova 5300 Series Portable Flue Gas analyzer is built on the NovaNOW next generation rugged portable platform. This series has been designed for accuracy, reliability, ease of use and ease of service, providing a detailed spot-check analysis of flue gas composition.

The 5300 uses customer-replaceable electrochemical sensors that respond quickly to the O2, CO, NO, NO2, and SO2 present in the flue gas sample. The O2 sensor life expectancy is typically 3-4 years. The CO, NO, NO2, and SO2 sensor life is typically 2-3 years. The infrared CO2 sensor should not need to be replaced under normal conditions of use.

A rechargeable lithium ion battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged. The 5300 series case is small but rugged and dust & water resistant when closed. Stack temperature measurement and built-in printer that also shows date & time are optionally available on any model.
