The small, hand-held and self contained GSR2(tm) is a Galvanic Skin Response monitoring device for home biofeedback. The GSR2 precisely monitors your stress levels by translating tiny tension-related changes in skin pores into a rising or falling tone. By resting two fingers on the sensing plates you learn to lower the pitch and your stress level. The GSR/Temp2X includes a temperature sensor for monitoring heat levels in fingers. Stress also reduces blood flow to the hands, causing cooling. The GSR2/Temp2X home biofeedback system allows you to do "hand warming" biofeedback.
