Our portable APU tester puts a test cell in your hand for on-wing testing of APUs. Simply connect our Signal Analyzer Unit between the ECU and aircraft, connect to your laptop, and you'll be able to monitor the engine in real time, as if you had it in your test cell.

All engine parameters are displayed in real time on your laptop screen. Select among digital, analog, bar graph, and strip chart displays. Readouts are color coded to show whether they fall within limits.

Test runs are saved in familiar Microsoft Excel spreadsheet form. You can easily make graphs for comparing selected engine readings--a great help in explaining a problem and deciding on a solution.

Avoid AOGs. Avoid swapping out engines and parts when you can diagnose the problem on-wing in minutes.
