A stainless steel movement and the as-welded Duratube Bourdon tube make the 1279 Duragauge safe and reliable for countless pressure cycles.
This solid front, 4½-in. pressure gaugeis available in dry, liquid filled or with the Plus! performance option to steady the pointer and protect the movement from vibration/pulsation without a liquid fill. Equipped with a diaphragm seal, the combination provides a wide choice of process connections, an optional flush port and wetted materials compliant to NACE standards.
