E Instruments tackles accuracy issues with the new E8500 Cooled NOx.
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 keeps the NO sensor cooled with an internal cooling system.
The analyser measures, displays and records the NO sensor temperature to make it easier to comply with US EPA conditional test methods such as CTM-030. The E8500 Cooled NOx also comes standard with our Sample Conditioning Unit (SCU). This SCU cools and dries the stack gas at the probe handle to minimise the time that the gas has in contact with the condensate.
