The very thin probe tip gives Longacre tire pyrometers rapid response. Unfortunately, it also makes the probe tip somewhat delicate and easy to damage. Bent or broken probe tips may give false readings or no readings at all.
This is the same tire probe supplied with all Longacre probe-type tire pyrometers, including our Part Nos. 3174 and 3174/Watch. The coiled cord makes it easier to use without tripping over a long, stiff cable. Temperature limit 300° F (150° C).
