Process Gauges (Solfrunt 4 1/2)

Series 1900 4 1/2" Solfrunt gauges are supplied in 30 different vacuum, compound and pressures ranging from 30" Hg vacuum through 11,600 psi. Any low-connected PET turret case or aluminum back flanged case gauge can be easily liquidfilled in the field using the appropriate conversion kit.

Calibration adjustments (scale shape and span) can be accomplished from rear of case without disturbing the gauge internals. Pointer adjustments are easily made by removing ring and window.
