The Keysight E2307A is a Type-K thermocouple bead temperature probe. It has a Type-K exposed welded thermocouple junction. Its No. 24 AWG wire is terminated in a 3/4 inch dual banana plug. The positive lead is of a nickel-chromium composition, and the negative lead is nickel-aluminum.

The E2307A can be used with the 34401A, however, it requires an external program to convert the voltage measurements to temperature.
