The SDP Static Ductprobes and TDP Total Ductprobes are ideal to measure a static pressure, total pressure or velocity pressure in ventlilation ducts, fan chambers , rooms or any other location where a pressure sample needs to be taken. They are manufactured in a 100mm and a 200mm length. They are made of Aluminium and the SDP has a straight opening and the TDP has a 90 degree bend at the end to pick up the pressure.

The MDF Duct Flowprobes are ideal to measure air volumes in round spiral ducts from 80 up to 500mm diameter (maximum 710mm with support bracket). The MDF produce an average differential velocity pressure to provide an air volume measurement for fan proving, VAV or CAV volume control in ducts and general ventilation applications. They are made of Aluminium and can be mounted easily by simply drilling a 25.4 mm round hole into the duct.

The RDF Flowprobes are ideal to measure air volumes in round,oval, rectangular and square ducts. They produce a stabile air volume signal ready to be used in any constant or variable air volume control, monitoring or alarming appliaction by BMS or Scada system intergrators when used in conjunction with the P-Sensors or any CMR Transmitters. They are made of Aluminium and can be mounted easily by simply drilling a 25.4 mm round holes into the duct.
