Aero Express will buy, sell and trade the 2548H depending on your needs.  The 2548H Fuel Quantity Test Set is a universal tester for AC Capacitance type systems. It is OEM accuracy and safety approved and requires no external power. It meets or exceeds the range, accuracy and safety requirements for fuel quantity systems up to 1000 pF and is designed to operate with guarded capacitance type systems. The tester can measure and simulate tank capacitance from 0.1 to 999.9 pF. It can measure insulation breakdown from 50 KW to 5000 M.W with an accuracy of ± 5% of reading nominal. The 2548H is a small, self-contained, battery powered, analog test set which can measure system insulation, capacitance, and simulate current to drive mA style indicators. The unit is small enough to use in confined places but accurate enough to use as a bench tester.


  • Measures capacitance of individual or interconnected tank units or unit simulators
  • Measures insulation resistance of wiring, tank units, or other discrete components
  • Simulates capacitance representative of empty, partially full or full tank units or systems
  • Low battery drain circuitry
  • 0.1 pF resolution throughout range
  • 2 terminal megohmmeter with 6 selectable test points
  • 3 terminal megohmmeter (optional on 2548H)
  • Adapter Cables are sold separately – see listing above for cable selection
