2.5˝ LOW PRESSURE GAGE
3-2-3% Full-Scale Accuracy in a 2.5” Gage
The Series LPG5 2.5˝ Low Pressure Gage offers top of the line performance for
pressure applications from 10 in w.c. to 10 psi. The LPG5 gages possess dual scales
with 3-2-3% full-scale accuracy on a 2.5˝ dial. Units are made with a chrome plated
steel housing and brass wetted parts. Units can withstand temperatures of -4 to 140°F
(-20 to 60°C). This series is meant for the measurement of low pressures of gases and
liquids and is ideal for air ow indication, liquid level and draft measurement. Series
LPG5 gages are available with either a bottom or back connection option.
FEATURES/BENEFITS
• Chrome plated steel housing and brass wetted parts resist ambient for longer
service life in harsh environments
• Low pressure gage provides a selection to meet specic applications
• Specied with high ambient and process temperature ratings mean more
robust uses and longer service-life
• Good accuracy gage for value-sensitive applications requiring more precise
measurement and where vibration is a concern
APPLICATIONS
• Air ow indication
• Liquid level
• Draft measurement

Our Series LPG4 2.5˝ Low Pressure Gage offers top of the line performance and
accuracy for pressure and vacuum applications up to and including 160 in w.c. The
LPG4 is constructed from a single beryllium-copper diaphragm afxed to a precision-
machined brass plate. This innovative design, together with a high-precision, milled-
teeth brass movement and nickel-silver pinion and bearing surface, provide the user
with a top of the line low pressure instrument.
