The Galvanic Skin Response Sensor connects to the expansion port on the Equivital SEM to enable recording of Galvanic Skin Response (GSR) signals. It consists of a small box that can fit inside the Equivital Sensor Belt or be worn on the wrist as well as short leads terminating in standard 'Snap Lead' connectors suitable for use with the MLA1010 disposable electrodes. Note that since the Galvanic Skin Response Sensor connects to the SEM's only expansion port this cannot be used in conjunction with any other accessory that uses this port (i.e the Equivital SEM External Battery Pack)

The Equivital SEM External Battery Pack increases the battery life of the SEM to 24-43 hours (depending on configuration used). Note that since the External Battery connects to the SEM expansion port it cannot be used in conjunction with any other accessory that uses this port (i.e the Equivital GSR Ancillary). It is just large enough to accomodate the 3 AAA size batteries it requires to operate and fits inside a dedicated pouch in the Equivital Sensor Belt.

The Wired SPO2 Adapter for Equivital consists of Nonin xPod device wired for direct connection to the ancillary port of an Equivital Sensor Belt. It is compatible with a range of Nonin SpO2 sensors (sold separately) such as the MLT321 Finger Clip. Cable length is approx 180 cm (6') and weight is 75g. Note that since the SpO2 sensor connects to the SEM ancillary port it cannot be used in conjunction with any other accessory that uses this port (i.e the Equivital GSR Add-On, or the External Battery Pack).
