The Series SG5 Contractor Gages are ideally manufactured for contractors because of their large dial and compact design. Since the gages are lightweight and slim, they are easy to transport. The large 4.5" scale makes them simple to read. The Series SG5 gages possess psi scales with 1% full-scale accuracy. The gages are made with a stainless steel housing and brass wetted parts. Units can withstand temperatures of -4 to 140°F (-20 to 60°C). These qualities make the SG5 series perfect for contractors and industrial applications. A wide offering of ranges are available from full vacuum to 300 psi.
