The B-Series 30Hg Vacuum Murphygage 20BVG-30 is a high quality, diaphragm-actuated indicating gage. Built by Murphy with the same heavy-duty design as the standard 20 series and 25 series Swichgage instrument, the B-gage is more compact and is the optimum instrument for gage-only applications. It has a high impact polycarbonate lens, sturdy steel case, and a polished, low-profile stainless steel bezel. Accuracy and protection from moderate over-pressure/over-temperature are assured by a unique, unitized diaphragm chamber, superior quality materials, and the design of the gage movement.
