Series SG1/SG3 1.5" Pressure Gauge

Brand: Dwyer Instruments, LLC
Does not ship to Virginia, United States
The Series SG1 Industrial Pressure Gauges are perfect for applications where resistance to corrosion is necessary.

The stainless steel case and ring offer excellent protection from harsh processes.

The SG1 gauges are an economical choice where ambient corrosion and vibration are a concern. Gauges are suitable for all fluids that are compatible with brass and bronze, and are available with bottom or back connections. 

The Series SG3 Industrial Pressure Gauges have dual psi and bar (x100 kPa) scales with ± 2.5% full-scale accuracy.

The Series SG3 gauges are designed with 304 SS housings and 316 SS wetted parts for excellent chemical compatibility.

These gauges cover a wide variety of ranges from full vacuum to 300 psi. Units can withstand ambient temperatures up to 140° F (60° C).

Bottom or back 1/8" NPT connection options available.
Features
  • Stainless steel housing to resist ambient corrosion for longer service life in harsh environments
  • Good accuracy gauge for value-sensitive applications requiring more precise measurement and where vibration is a concern
  • Back or bottom mounting and compact size provides for mounting with dimensional limitations
