Six Cylinder EGT and CHT Combination Kit with Probes

The ECT2046 is a full color EGT and CHT combination instrument that provides simultaneous, real-time display of all six cylinders. This kit includes six Type-K ungrounded, EGT thermocouple probes of your choice, six Type-J ungrounded, CHT thermocouple probes of your choice and , all connectors and installation hardware.

Both Cylinder head and Exhaust gas temperature functionality is TSO'd and meets the temperature accuracy requirements of SAE AS8005 for a Class IIa (+/- 1%) instrument. Functional displays include:

  • Real-time six cylinder temperature display
  • Menu select option for fast selection of display type
  • Automated rich-of-peak (ROP) leaning function for EGT
  • Automated lean-of-peak (LOP) leaning function for EGT
  • Automated shock cooling monitoring for CHT
  • Single cylinder temperature monitoring while retaining graphic indications for all cylinders (Both CHT and EGT simultaneously)
  • Graphic trend analysis and viewing of all cylinders simultaneously (selectable for EGT or CHT)

The ECT2046 kits are TSO'd and STC'd as a primary replacement instruments under all flight conditions (day/night VFR and IFR).
