The GSR module is self contained. Readings can be taking using the fingertip pads on the module, or the two electrodes can be placed on any body part. The GSR module gives an audible feedback (earphone comes standard and can be plugged in to the unit) or a visual feedback (optional meter meter can be plugged into the unit).
The temperature module included with this item comes with a temperature probe that attaches directly to the GSR for either audio or visual meter feedback (temperature meter comes with unit).
The visual feedback meter (FE-154267) is sold separately.
