Eight Cylinder EGT Kit with Bayonet Probes

The ET208 is a full color EGT instrument that provides simultaneous, real-time display of all eight cylinders. This kit includes eight Type-K ungrounded, bayonet type thermocouple probes, all connectors and installation hardware.

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 eight cylinder temperature display
  • Menu select option for fast selection of display type
  • Automated rich-of-peak (ROP) leaning function
  • Automated lean-of-peak (LOP) leaning function
  • Single cylinder temperature monitoring while retaining graphic indications for all cylinders
  • Graphic trend analysis and viewing of all cylinders simultaneously

The ET208PB is TSO'd and STC'd as a primary replacement instrument under all flight conditions (day/night VFR and IFR).
