Item # 375 Series, Portable Flue Gas Analyzer for Oxygen, Carbon Monoxide and Carbon Dioxide


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 digital meters which have a switchable backlight for use in dark areas. A special water separating filter and seperate drain pump continuously remove condensate from the sample so the analyzer can be operated for long periods unattended.

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 'gel cell' battery provides enough power for about 16 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The recharger is included.
