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