pressure gauge / liquid-filled Bourdon tube / analog / vacuum / stainless steel

The Models 1981 and 1981 Advantage 4-1/2" are specially designed to provide an extensive and maximum performance for several applications. They are process gauges mainly built for several process applications which has a high demand for panel mounted gauge. The Models 1981 and 1981 Advantage 4-1/2" SOLFRUNT gauges are mainly supplied with 21 vacuums, compounds and pressure which runs from 30? Hg vacuum up to 11600 psi. The calibration adjustments integrated in the models such as the scale shape and span can be achieved from the rear of the case without interrupting the gauge internals. The PET material of the apparatus provides the case with a maximum impact strength and a wide range of chemical tolerance. They are available either dry or in liquid filled from the factory.
