SOLFRUNT® 4-1/2" Models 1403 and 1404 Test Gauges

Series 1400 4-1/2" SOLFRUNT test gauges are designed to combine laboratory test gauge accuracy with carrying case or rolling test stand portability, and frequently are permanently installed on instrument shop test benches or test panels.

These gauges feature a ±0.25% accuracy (Grade 3A) solid front case, which provides a partition between the pressure measuring element and the window, with a pressure relieving back.

Accurate gauge reading is accomplished by sighting the knife edge of the indicating pointer with the paralleling pressure graduation, while simultaneously eliminating the pointer’s image on the mirrored dial edge.

An adjustable pointer provides front zero adjustment.

Other calibration adjustments can be made from the back without removal from the case.

Metric ranges are available upon request.
