Four Cylinder CHT Kit with 14mm Ring Probes
The CT204 is a full color CHT instrument that provides simultaneous, real-time display of all four cylinders. This kit includes four ungrounded 14mm ring thermocouple probes, all connectors and installation hardware.
Cylinder head 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
- Single cylinder temperature monitoring while retaining graphic indications for all cylinders
- Graphic trend analysis and viewing of all cylinders simultaneously
- Programmable shock cooling monitor and indication
The CT204R4 is TSO'd and STC'd as a primary replacement instrument under all flight conditions (day/night VFR and IFR).
