Skin Conductance Unit
The 2502SA stand-alone skin conductance unit is designed to take direct measurements of the conductivity between two skin electrodes by maintaining a 500mv DC potential across them, and then measuring the current needed to maintain this potential. This current value is then represented and output as a scaled voltage, suitable for connection to a CED 1401 laboratory interface.
The 2502SA uses the constant-voltage principle and has manually switched conductance ranges of 10, 25 and 100 micromhos. The sockets accept 1.5 or 2 mm plugs.
The CED 2502SA is offered as research equipment and is not sold as a medical device within the meaning of the European Medical Device Directive.
