Galvanic Skin Response Measurement Device Frederiksen
Our Frederiksen Galvanic Skin Response Measurement Device measures fluctuations in galvanic skin response (GSR) in humans. Fluctuations in galvanic skin response occur when people are exposed to situations which can cause stress or anxiety. These situations could be questioning, mental challenges or influences from flavour or sound stimuli. GSR measurements also form part of the much debated "lie detector" tests used past and present all over the world.
The biofeedback is obtained when skin electrodes are placed on two fingertips. Exposal to external stimuli causes changes in the relative conductance over the skin surface of a small electrical current, which runs between the two skin electrodes. With the GSR-device these measurements can be recorded with a datalogger/interface or a simple voltmeter (none of these included).
This Galvanic Skin Response Measurement Device has primarily been developed to work with datalogger equipment from Pasco, but will also work with other systems and voltmeters. The GSR-device is supplied with battery, cables and self-adhesive skin electrodes (100 pieces).
Not included: Datalogger/interface equipment or voltmeter for data sampling.
