Nine Cylinder CHT Kit with 18mm Ring Probes

The CT209 is a full color CHT instrument that provides simultaneous, real-time display of all nine cylinders. This kit includes nine ungrounded 18mm 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 nine 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 CT209R8 is TSO’d and STC’d as a primary replacement instrument under all flight conditions (day/night VFR and IFR).
