Here is a lead for GSR equipment. Of course I would argue that the best method for measuring emotional arousal and intensity is fMRI, but it is expensive.

Description from web site:

The GSR meter instantly and accurately measures your emotional and

physical arousal. Simply hold it in your hand, resting two fingers

on the sensing plates. It turns itself on automatically at the

touch of your fingertips and emits a tone. The more stress you

feel, the higher the tone. Includes the GSR2 biofeedback unit plus

instructional cassette.

** GSR units are like OHM METERS, that is, they depend on passing 

a small current through the person or plant being tested.  This 

current though safe and small, can irritate skin and leaves, and 

this is why a current-lowering circuit modification is being worked

on.  Meanwhile, a 470K (470,000 or "half meg") resistor in series 

with one of the leads can be used to lower current without preventing

the pickup of skin response or leaf response.
