Four Cylinder EGT and CHT Combination Kit with Probes
The ECT204 is a full color EGT and CHT combination instrument that provides simultaneous, real-time display of all four cylinders. This kit includes four Type-K ungrounded, EGT thermocouple probes of your choice, four 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 four 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 ECT204 kits are TSO'd and STC'd as a primary replacement instruments under all flight conditions (day/night VFR and IFR).

Q: Can this instrument be configered for centigrade temp display. Also are the norm, warning and alarm temps programmable.
Yes, this instrument can display temperature in centigrade, and all limits are programmable.
Q: I have the AEROSPACE LOGIC 6 cyl CHT instrument on a jabiru 3300. I want to replace some of the probes due to damage at the spark plug ring. Please advise if universal probes will do or do you recommend other provider?
Yes, universal probes will work as long as you use Type J wire for CHT and Type K for EGT.
Q: Can I use the Aerospace Logic four cylinder in the rotax 912 engine?
Yes, this will work on the Rotax 912.
Q: Is there a alarm trigger outlet for a voice announciator?
Per the installation manual, yes, this unit does have an annunciator output.
