Continuous moisture detection and monitoring in medical and pure gases such as O2, thanks to our moisture monitor the DET H2O. 

According to the monography n° 1238 « Medical Air » of the European Pharmacopoeia, the highest admittable water amount for an air qualified of « breathable » is of 67ppmV (dewpoint at -45°C).

Medical air (composed of 22% of oxygen and 78% of nitrogen) is used as a carrier gas to dilute anaesthetic substances such as Nitrous oxide.

This electrochemical measuremetn method gives very precise values (scale of 0,5ppmV) and between 0-10 or 0-1000ppmV, even in ppb according to the specificity of the request.
