Series SGP/SGO Stainless Steel Schaeffer Gauge

Brand: Dwyer Instruments, LLC

The Series SGP and SGO Gauges have dual English/Metric scales with ± 1.6% full scale accuracy.

The Series SGP gauges are designed with 304 Stainless Steel housings, a 316L Stainless Steel chamber and a 316 Stainless Steel diaphragm for excellent chemical compatibility. 

Units can withstand ambient temperatures up to 149° F (65° C) and process temperatures up to 248° F (120° C).

Ranges of vacuum, compound and pressures to 235" w.c. are available.
Features
  • Stainless steel housing and wetted parts resist ambient corrosion for longer service life in harsh environments
  • Wetted parts permit use in chemical applications
  • High accuracy gauge for applications requiring more precise measurement
  • Models that support vacuum to higher pressure ranges provide a selection to meet specific applications
  • Specified with high ambient and process temperature ratings mean more robust uses and longer service-life
