CHT Probes in 10, 12, 14 and 18mm size

Currently we offer four different versions of our CHT probes. These are all "K-type" thermocouples and they come in sizes 10mm, 12mm, 14mm and 18mm. The sizes refer to the thread diameter of the spark plug the probes are used on. Most automotive engines and Rotax two strokes use 14mm plugs, the Jabiru engines and Rotax 912/914 use 12mm plugs. Lycomings and Continentals use 18mm plugs. The 10mm ring can be used under bolts to measure such things as gearbox temp.
The probes are supplied with 3ft 7in of fibre glass insulated cable, heat resistant to 300 degrees C.
