GSR2 with Temperature Probe

The addition of the Temperature Probe to the GSR2 instrument makes it useful in situations where your goal is to control blood circulation. This may be to treat migraine, where Biofeedback allows you to raise the temperature of a finger, which has been found to be helpful to migraine sufferers who learn to abort imminent attacks of migraine. It is also used to relieve dysmenorrhea and Raynaud's syndrome. See:-
