Signal’s analysers are recognised as the best practical analytical method for NOx detection in a wide variety of applications.
This is a term generally meaning the sum of nitric oxide and nitrogen dioxide. There are two widely used methods for measuring NO, infra-red and chemiluminescence, NO2 is then measured by first converting it to NO using a catalyst, to give a reading for the total NOx. NO and NO2 can also be measured at low levels in ambient air using electrochemical cell technology. This is a lower cost alternative but has limitations in terms of accuracy due to potential cross sensitivity and high temperature and humidity effects.
Non Dispersive Infrared (NDIR) Multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.
Chemiluminescent Detector (CLD) NOX analysers for NO/NO2/NOx measurement in engine emissions, combustion studies, process plant, Emission monitoring and medical gas production.

Levels of uncertainty in gas measurements can be increased, for example, by calibration gases that offer poor levels of accuracy. For this reason, Signal Group
Responding to a demand for short-term monitoring, Signal Group has established a fleet of gas measurement instruments that are available for hire. “Some of our
