1. An improved thermometer for hot asphaltic concrete application comprising:

  • (a) a housing, said housing having a first portion containing a thermometer body and a spool assembly for storing a cable and a second portion having a slot therein for removably storing a temperature sensing probe;

    (b) a temperature sensing probe, said temperature sensing probe further comprising a housing having a slot therein and an extendable sensing portion pivotally connected to an end portion of said housing, and whereby said extendable sensing portion may pivot between a retracted position within said housing when said thermometer is not in use and an extended position when said thermometer is being used to facilitate measuring temperatures of hot asphaltic concrete at increased depths; and

    (c) a cable connecting said thermometer body and said temperature sensing probe, said cable being adapted to transmit a sensed temperature from said temperature sensing probe to said thermometer body for indication of said sensed temperature;

    (d) whereby said spool assembly facilitates extension and retraction of said cable.
