The Heavy Duty pressure gauges with glycerine filling are used at measuring points with high dynamic alternating loads and strong vibrations and pulses. The glycerine filling ensures smooth pointer movement and thus good readability even in extreme load and strong vibration conditions.
The lubricating effect of the glycerine also provides protection against increased wear. The modern modular construction system with an o-ring sealing system, tried and tested for many years, ensures a high level of functional safety and a long service life.
Case components are composed of stainless steel.
Please Note: Due to a factory change, the P1778 Gauges will be phased out and replaced by the P1776 Gauges. The only difference will be the P1776 Gauges have a rolled bezel. Refer to the P1776/P1777 Data Sheet
