This new NOx analyzer has an internally cooled sensor

The accuracy of an NO gas sensor, the primary component of NOx, can be compromised when exposed to ambient temperatures above 86°F (30°C) and significantly more so above 104°F (40°C). To help prevent this temperature effect on the NO sensor, the E8500 Cooled NOx portable emissions analyzer (photo) keeps the NO sensor cooled with an internal cooling system. The analyzer measures, displays and records the NO sensor temperature to make it easier to comply with conditional test methods. The E8500 Cooled NOx also comes standard with this company’s Sample Conditioning Unit (SCU), which cools and dries the stack gas at the probe handle to minimize the time that the gas has in contact with the condensate. — E Instruments International, LLC, Langhorne, Pa.
