There is disclosed a device for telemetry of the temperature of a mass undergoing temperature change, typically of a comestible being heated in an oven, and the like. The device includes a probe having a cavity which receives a thermally expansive material such as wax, a displacement member responsive to pressure developed by the temperature expansive material, a sonic or ultra-sonic signal generator, a latch mechanism inhibiting operation of the audio signal generator and a rod mechanically interconnecting the displacement member with the latch so that expansion of the material in the probe cavity trips the latch mechanism to permit generation of an output signal. The device also includes adjustment means for variation in the relative positions of the latch mechanism to the displaceable member whereby the triggering temperature for the latch mechanism can be fixedly adjusted.
