The highlights

Controlled Humidity Generator

A dry gas and a humidity–saturated gas are mixed in order to produce a gaseous flow with a controlled and stable humidity rate of ±0.3% RH, at a given temperature.
Programming is done by EURTOHERM devices that incorporate the humidity and temperature measurement of gas flow and their precise control, permitting the formulation of humidity profiles (ramp, plateau, humidity rate incrementation…).

Wetsys can operate with different gases: He, Air, Ar, Ar, N2, CO2. Its main features are:
– Temperature range: RT to 70°C.
– RH (Relative Humidity): 5–95%.
– Flow rates: 20 to 50 ml/min.
– Autonomy > 1000 hours.
– Heated transfer line: RT to 85°C.
