Pressure Gauges

Model Chart

Specifications

Pressure gauges for continuous indication of air

pressure in pneumatic control systems.

Features:

• Permits readout of main air pressure and/or output

pressures of pneumatic control components.

• 0 to 100 (0 to 700 kPa) and 0 to 30 psig (0 to 200 kPa or 0

to 210 kPa) models available.

• Available in flush-mounted or stem-mounted models.
