New Call-to-action
The Nova 360 Series are portable analyzers that can provide a detailed analysis of flue gas composition. They have been designed to be accurate, reliable, and easy to use and maintain. The sensors respond quickly to the oxygen and carbon monoxide (CO) present in the flue gas sample. The typical sensor life expectancy is between 3-4 years and they are customer-replaceable.

In operation, a built-in sample pump draws in the flue gas sample through the S.S. probe, 12 ft. sample hose, condensate removal filter, secondary filter and flow meter, then on to the three sensors. The detected O2 and CO are displayed on separate LCD digital meters, which have a switchable backlight for use in dark areas. A special water separating filter and separate drain pump continuously remove condensate fro teh sample so the analyzer can be operated fro long periods unattended.

The Nova 360T indicates net 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 indicates when to recharge and a green LED verifies that it is receiving recharging power. The charger is included with the analyzer.  The rugged dust-tight and water resistant case is suitable for use in harsh environments.
