The Aerospace Logic CT206R8 is a six-cylinder cylinder head temperature (CHT) monitoring kit with 18 mm ring-type probes. It combines the CT206 full-colour CHT instrument with six ungrounded A200-TCR-18 thermocouple probes for simultaneous, real-time indication of all six cylinder temperatures. The manufacturer identifies this configuration for use on Continental O-300 engines only.

The kit includes the CT206 instrument, six 18 mm ring probes, connectors and installation hardware. The display provides all-cylinder temperature presentation, selectable single-cylinder monitoring while retaining graphical indications for the remaining cylinders, trend-graph viewing, and programmable shock-cooling monitoring. Temperature units are selectable in °C or °F.
