In addition, a heater may be provided in the probe and the control may be connected to regulate the heater. In the preferred arrangement, the control includes a device for setting the temperature value of operation which is connected to a comparator to provide a control between the set value and the actual value of the temperature of the body in the vicinity of the probe. |
