Item # 312 Series, Portable Flue Gas Analyzer for Oxides of Nitrogen


The Nova 312 Series Portable Flue Gas Analyzer for NOx utilizes a reliable, stable nitric oxide (NO) sensor which responds quickly to the NO present in flue gases or engine exhaust. NO is the major component (90-95%) of the NOx found in flue gases or engine exhaust (except diesel).

In operation, a built in sample pump draws in the gas sample through the S.S. probe, 12 ft sample hose, condensate removal filter, secondary filter and flowmeter then on to the NO sensor. The detected NO is displayed on a LCD digital meter which has a switchable backlight for use in dark areas.

The rechargeable battery provides enough power for about 20 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.
