SG3 pressure gauges are on the market in 1.5 and 2.5-in. designs.
They offer dual psi and bar (x100kPa) scales with ±2.5% full-scale accuracy. Designed with 304 stainless steel housings and wetted parts, the instruments offer outstanding chemical compatibility. They cover a wide full vacuum to 300 psi range and withstand up to 140°F. / 60°C. ambient.
SGZ gauges offer the same scales with ±1.5% full-scale accuracy. With the same constructions as SG3 they cover a wide range in either bottom or back connection configurations.
SGZs employ an easy-open breather plug on top to allow liquid-filled units to breathe — relieving any built-up internal pressures.
