These were fitted to a large variety of aircraft. They were commonly found on C-47's and C-54's. You will need iron-constantan leads with a resistance of 8 ohm to operate this instrument. You can use either a spark plug type thermocouple or a bayonet type. When fitting the bayonet type thermocouple on aircraft, there is an Pratt and Whitney Engine Operation Information Letter and Service Bulletin to follow.
