15.5mm symbol tube manufactured by Nanchang

The QS30-33 is a clear glass symbolic nixie tube that can display the units "F" for Farads, "µF" for Microfarads, and "PF" for Picofarads. These are units for capacitance in electronics, therefore it is likely that this tube was designed and used for capacitance meters.
