Series SGO Stainless Steel Schaeffer Gage

1.6% Full Scale Accuracy, 316L SS & PTFE Wetted Parts

The Series SGO Gages have dual English/metric scales with ±1.6% full scale accuracy. The Series SGO gages are designed with 304 SS housing, a 316L SS chamber and PTFE coated 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 are available from full vacuum, compound to 300 psi.

Calibration Option available under Accessories.

We are in the process of phasing this series out.
