The SU4 will reduce the pressure from the dryer to give a flow suitable for measurement. It combines a pressure reduction control, sensor holder and a flow meter for up to 10 litres per minute. (1-2 litre is usual for continuous use).

Moisture measurement under pressure will not give the correct answer but room pressure used in the SU4 will read correctly.
