Digital Pressure Gauges Product Description

Our highly accurate PG300 Digital Pressure/Altitude Gauge is compact and robust, making it well suited for a variety of pressure and feet of water column applications. The PG300 Digital Pressure Gauges backlit LCD display makes it easy to read, and it includes a zero reset button and pressure unit selection button (PSI, FT of WC (Water Column), and BAR).

Unlike mechanical pressure gauges, the PG300 Digital Pressure Gauges allows you to use a much larger range because of its high accuracy and digital readout. For instance, a 100 PSI PG300 Digital Pressure Gauges will work in place of any standard mechanical gauge from 15 PSI to 100 PSI, so you will only need one or two PG300’s to cover all your pressure or altitude gauge needs.

NOTE: The Digital Pressure Gauges electronics enclosure is NEMA 4X wash down rated. It is not submersible.
