2.2Pressure Connection

The pressure port is a G1/8. If a pipe is connected to this port a bonded seal must be used. The instrument is very sensitive to air movement (small local pressure changes), when the pressure port is directly sensing the atmosphere, the fitting of a filter or restrictor is recommended.
