New Call-to-action
The Nova 350 Series Portable Flue Gas Analyzer has been designed for accuracy, reliability, ease of use and ease of service. It uses customer replaceable sensors which respond quickly to the Oxygen (O2) and combustibles present in the flue gas sample. The sensor life expectancy is between 3 and 4 years.

In operation, a built in sample pump draws in the flue gas sample through the stainless steel probe, 12 ft. (4 m) sample hose, condensate removal filter, secondary filter, flow meter, then on to the oxygen and combustibles sensors. The detected O2 and combustibles are displayed on LCD digital meters which have a switchable backlight for use in dark areas. A built in air makeup system ensures that the combustibles detector will always have sufficient O2 for proper operation regardless of sample O2 content.

A rechargeable battery provides enough power for about 6 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.

The Nova 350T indicates stack temperature for doing fuel efficiency calculations. The temperature sensor is built into the sampling probe. Efficiency charts for each fuel are provided
