PBX High Accuracy Pressure Gauge by Rhomberg

PBX High Accuracy Pressure Gauge by Rhomberg   

The Rhomberg PBX pressure gauge is ideal for applications were high accuracy and durability is required and where the risk of Bourdon tube failure could compromise the safety of the operator.

All gauges are retro-fillable and totally repairable. A number of optional accessories are available either as factory fitted or retro-fitted. A Rhomberg vibration free movement [VFM] can be fitted where filling material is not allowed or excessive vibration is present.

The 54mm dial size safety pattern design is especially suitable for welding and medical gas regulators. Solid front baffle and flimsy back blow-out for all bottom entry gauges to meet SABS and U.L safety requirements as standard.
