3D Pressure Gauges

3D Instruments is a premier manufacture of pressure gauges. Their unique, "Direct Drive", helically wound bourdon tube design has only one moving part made of Inconel® X-750, a flexible material that prevents the coil from losing its shape and thus ensuring accuracy. With no additional mechanical components vulnerable to wear, a direct drive pressure gauge lasts longer than C-shape Bourdon tube pressure gauges, thus reducing down time and total cost of ownership.

3D Instruments manufacture the following:
Process pressures gauges, Test pressure gauges, Precision test pressure gauges, Skydrol Pressure Gauges, Refrigerant pressure gauges, switch pressure gauges, vacuum pressure gauges, compound pressure gauges, low pressure pressure gauges, sanitary pressure gauges, Custom and OEM pressure gauges. Their rang also extends to diaphragm seals, snubbers, valves and other pressure gauge related accessories
