The new S4 AURORA Paramagnetic oxygen analysers provide accurate percent measurements in combustion testing, inert atmospheres, medical and safety for humans, internal combustion engine exhausts and many more applications. With a remote software suite for control over the Internet, and an optional wireless tablet, the S4 AURORA is simple to operate. To ensure flexibility, users are able to specify their required configuration and programmable contact closures are available for gas path control. In common with all S4 analysers, the AURORA range deliver outstanding performance – 0.01% resolution and 0.1% linearity.

FID: the VOC emissions monitoring reference method – for over 50 years!
The Flame Ionisation Detection (FID) method was first developed in the 1950s for the laboratory analysis of organic chemicals. Later, when environmental regulations began to limit the emissions of volatile organic chemicals (VOCs) in the 1970’s and 1980’s, the FID method was adapted for emissions monitoring.
