MN25 DN150 Bourdon Tube Test Gauge

Brand: Nuova Fima

These instruments have been designed for laboratories, instrument testing or recalibration facilities and to be used in other applications where accuracy and repeatability are of primary importance. 

These instruments have a solid separating wall in stainless steel, placed between the dial and the elastic element and an integral blow out back that is released from the case whenever a pressure is created inside the case, due to leaks or accidental ruptures of the elastic element. 

The process fluids should be gases or liquids, they must not have high viscosity and must not crystalize. 

The wetted parts in AISI 316L allow to use them in the worst working conditions determined by aggressive medium and environment. 

Upon request we can supply the calibration certificate issued by an Internationally recognized laboratory of ACCREDIA (Ex S.I.T. - Italian Calibration Service).
