The design of instrumentation for the ambulatory measurement of skin conductance (SC) is discussed. Two problems which are frequently encountered concern size constraints and the provision of a sufficient dynamic range. A circuit description which overcomes these problems is given along with details of its construction. This device utilises an AC-coupled amplifier stage for Skin Conductance Responses (SCRs) and a DC-coupled amplifier stage for Skin Conductance Level (SCL). Its use in conjunction with a portable instrumentation cassette recorder is described.
