SERIES SGX & SGF | 2.5˝ STAINLESS STEEL LOW PRESSURE GAGES

FEATURES/BENEFITS

• Stainless steel housing and wetted parts resist ambient corrosion for
longer service life in harsh environments

• High accuracy gage for applications requiring more precise measurement

• Models that support vacuum to higher pressure ranges provide a
selection to meet specic applications

• Specied with high ambient and process temperature ratings mean more
robust uses and longer service-life

• Field adjustable zeroing screw simplies installation and calibration

APPLICATIONS

• Pneumatic

• Draft measurement

• Filter monitoring

• Liquid level

DESCRIPTION

The Series SGX & SGF 2.5˝ Stainless Steel Low Pressure Gages have dual English/metric
scales with ±1.6% full scale accuracy. The Series SGX/SGF gages are designed with 304 SS
housings and brass or 316 SS wetted parts. Units can withstand ambient temperatures up to
149°F (65°C) and process temperatures up to 212°F (100°C). Ranges of vacuum, compound
and pressures to 235˝ w.c. are available. Included on the dial is a convenient zero adjustment
screw which allows the user to easily re-zero the needle.
