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 precision­machined brass plate. This innovative design, together with a high-precision, milled­teeth brass movement and nickel-silver pinion and bearing surface, provide the user
with a top of the line low pressure instrument.

FEATURES/BENEFITS

• 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

• High accuracy gage for applications requiring more precise measurement is a

concern

APPLICATIONS

• Air ow indication

• Liquid level

• Draft measurement
