APPLICATIONS
Analysis of oxygen ( O2) , carbon monoxide ( CO) , carbon dioxide
( CO2) and oxides of nitrogen ( NOx as NO) . For checking the combustion
efficiency, and burner & control performance of furnaces, heaters,
and boilers. May be used in commercial, industrial, and residential
settings.

DESCRIPTION
The Nova 376 Series Portable Analyzers provide a detailed analysis of flue gas composition. They have been designed for accuracy, reliability, and ease of use and service. The sensors respond quickly to the gases of interest present in the flue gas sample. Under normal conditions of use, the O2 sensor life expectancy is between 3 and 4 years. The CO and NOX sensor life is 2-3 years. The O2, CO, and NOX sensors are customer-replaceable. The CO2 sensor 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 flowmeter, and then on to the four sensors. The detected O2, CO2, CO, and NOX are displayed on digital meters which have a switchable backlight for use in dark areas. The sensors do not require special SO2 scrubbing chemicals as do some types of analyzers.
The Nova 376T 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.
