. An inexpensive and reliable electronic device is described which allows measurement, viewing and recording of electroantennogram (EAG) responses. Potential advantages of the device include low cost, simple operation, suitability for bench or field use, built‐in digital readout, separate head amplifier, (+) and (‐) peak value memories, and an exclusive automatic offset and drift cancelling circuit which does not introduce distortion. The device is intended for use in EAG recording, where signals with either rapid or slow depolarizations are being measured, bringing important information in the return‐to‐baseline region, as well as the (+) and (‐) peak values of the EAG.
