Calibration of dynamic gas mixers and mass flow controllers in the low flow range.

english & deutsch

Hydrogen, methane, CO ???

Working with flammable or toxic gases ?

We offer an integrated safety module for our gas mixers with :     - internal gas sensors for leak detection,

-  warning lamp, audible alarm,

-  immediate shutdown of the gas mixer and

-  automatic flushing of the enclosure with inert gas : the AlarmModule


Gas mixers for corrosive gases

Most gas mixers can't be used with corrosive gases ... now we have the solution : the combination of standard / combustible gas channels and corrosive gases in ONE instrument. 

NEW features for GMS gas mixers : Connect to Internet

GMS gas mixers : GMS with internet connectivity

Internet connection by TCP Client / Server functions : 

allow data transfer and control of the gas mixer via Internet.

Calibration of dynamic gas mixers and mass flow controllers in the low flow range

Most dynamic gas mixers use flow regulators to create defined gas mixtures. QCAL Messtechnik uses thermal mass flow controllers ( MFC ) from various, renowned manufacturers. These MFCs are reliably calibrated proven by a calibration certificate – traceable to National Standards. But these calibrations are limited .....
