compressed air connection that delivers maximum 17.5 Nl/min at a pressure
of 2...5 bar. The pressure required depends on the negative pressure in the
system from which the measurement gas is extracted.
A compressed air conditioner is supplied with HYGROPHIL
®

accessory. It contains a reducing valve that can be used to set the
necessary pressure.
