Dwyer Instruments' Series SGY gages have dual psi and bar scales
Dwyer Instruments' Series SGY gages have dual psi and bar (x 100 kPa) scales with ±1.5% full-scale accuracy. The Series SGY gages are designed with 304 stainless steel housings and brass wetted parts. The gages are built to cover a range from full vacuum to 1,000 psi and are available in both bottom or back connections. Series SGY gages employ a breather plug on top, which allows liquid-filled units to breathe. The plug pops open and does not need to be entirely removed or cut.
