Designed for gas or general compressed air sampling

Product details

The Shaw Moisture Meters Model SU4 sample conditioning unit is designed to reduce the dryer/process line pressure to give a pressure and flow suitable for measurement.

The system is designed for gas or general compressed air sampling and allows the sensor to operate at atmospheric pressure. 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).

The SU4 is suitable for wall mounting, comprising a pressure regulator, flow indicator and sensor holder mounted on a stove enamelled backplate. It conditions the flow of sample gas to the required 2 – 10 litres per minute at near atmospheric pressure for accurate and consistent sampling. Pneumatic connections with a choice of ⅛”, ¼” or 6 mm compression fittings are available, if required, for inlet and outlet.
