Condition: Excellent – Lightly Used / Stored Indoors

Available for sale is a Preston Pressure PS-425 Pitot-Static Tester, a portable and reliable test set designed for aircraft pitot-static system testing and maintenance. This unit was originally purchased for use in a third-party maintenance operation but was never placed into regular service, remaining stored indoors in very clean condition.

The unit powers on and functions as expected and would make an excellent addition for avionics shops, A&P mechanics, or aircraft maintenance facilities requiring a dependable portable test system.
