The model MM-111 probe (type K) is applicable to any type of aircraft exhaust gas temperature indicator that uses type K thermocouple as its electrical source. The MM-111 is designed to universally replace all chromel alumel (type K) thermocouples regardless of manufacturer or design. The Universal MM-111 probe is FAA/PMA approved.

With the Universal MM-111 probe you receive the benefits of unique, non-welded construction utilizing a new, exclusive, space-age technology. This assures you thousands of hours of trouble-free operation. The faster, almost immediate response to temperature changes results in better control of engine performance. Installation is simple and requires no welding or special tools. The MM-111 offers superior performance at a reasonable price.

Please note, all thermocouples/probes regardless of manufacturer are identified by the color of their terminal lead wires. A type K thermocouple/probe will have one wire color coded red, and the other yellow.
