The Series SG3A Sanitary Pressure Gage ismade to 3-A sanitary standards and offers several size and pressure rangeoptions, which make it ideal for many sanitary applications particularly in thedairy, food processing, and pharmaceutical industries. The Series SG3A SanitaryPressure Gage is available with 2″ or 2-1/2″ with an accuracy of 1.5%or 2% depending on range. The dials of the Series SG3A Sanitary Pressure Gageare available for vacuum, compound and positive pressure applications. The3/4″ or 1-1/2″ sanitary fittings of the Series SG3A create a sanitaryprocess connection available on either the back or bottom of the gage. TheSeries SG3A can also be ordered with food grade Glycerin in the dial to reduceinaccuracies caused by vibration to the dial indicator
