Abstract
An electric soldering iron has a barrel connected to a handle a one end and provided with an electric heating element for heating a tip at its other end. A detachable temperature sensor unit is located within the barrel and includes a tubular housing having a temperature sensor projecting from one end and positioned within a hollow bore in the tip to monitor the temperature thereof and electrical contacts on its other end readily detachably connected to electrical contacts of a heating control unit located within the handle. Either the temperature sensor or the housing is spring biased to urge the temperature sensor into close proximity with the tip.
