SERIES LPG3 Low Pressure Gages are designed to be especially sensitive with an
elastic element that expands and contracts with very small changes in pressure for
ASME Grade 1A accuracy. This series is meant for the measurement of low pressures
of gases and liquids and is ideal for air ow indicators, liquid level indicators and draft
gages. Our new low pressure gages are available in 2-1/2˝ dial with either a bottom or
back connection option.
