| Marsh Instruments' Severe Service line features a regged impact and corrosion resistant ABS case gauge that is hermetically sealed. It is available dry or liquid filled. The liquid filling dampens the damaging effects of pulsation and vibration common to many hydraulic systems. It also lubricates the internals and reduces corrosion. The ultrasonically welded acrylic window and two piece socket design ensure superior, leak free performance. |
