Note 1) Pressure display means a pressure gauge or digital pressure switch is attached.
When choosing to attach a digital pressure switch is chosen for attachment, be sure to enter the
symbol, referring to table 8, “Digital Presure Switch Output Specifications”. Otherwise, a
pressure gauge will come with the regulator.
Note 2) Pressure gauges are not compatible with copper-free and fluorine-free specifications.
Note 3) Pressure switches are not available with the oil-free specification.

Note 1) This option is available for use outside Japan only.
(The SI unit has to be used in Japan.) Additionally,
the pressure switch offers dual unit presentation in
MPa and psi.
Note 2) The digital pressure switch is equipped with unit
switching and initially set to psi.
Note 3) This option is available with the digital pressure
switch. A lead wire with connector (2 m) is included.
Note 1) A pressure gauge with a full span of 0.4 MPa is attached.
Note 2) The oil-free specification is grease-free in the fluid contact area.
