Nitrous Oxide

Signal make a range of analysers for nitrous oxideto comply with the latest EPA regulations and ISO21258 for automotive and other applications.

Nitrous Oxide, or laughing gas, is a relative newcomer to the list of industrial pollutants of concern to regulatory bodies monitoring climate change. It has a stronger greenhouse effect than carbon dioxide and is produced as a by-product of many industrial processes.

The measurement techniques available for this gas are infra-red and electrochemical cell. Both have their limitations. The US EPA have produced guidelines on what they consider to be the reference method for measuring N₂O as part of the process of legislating for it to be measured and reported by engine and vehicle manufacturers and other industries. They suggest using an infra-red detector that uses a catalyst to oxidise CO, the strongest interferent.

S4 PULSAR

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.
