The EOG100C amplifier can record from DC to 100 Hz and is designed to measure a signal correlated with the corneal-retinal potential (the small electrical potential difference between the cornea and the retina which probably results from the higher metabolic rate of retinal tissue). EOG is useful for recording eye movements. With electrodes placed around the eyes, the recorded signal will vary with eye position as the cornea moves closer to one electrode and farther from the other (as the retina does the opposite). The corneal-retinal potential does not vary with eye position, but the extent to which the electrodes experience the effects of that potential vary with eye position.
The EMG100C amplifier can record from 1 Hz to 5000 Hz and is designed to measure muscle biopotential signals. It is intended for higher frequency measurements and cannot be used to record DC potentials.
Although the amplifiers are designed to pick up different signals, the EOG100C can pick up some EMG activity (whatever part of the signal is under 100 Hz) and the EMG100C can pick up some EOG activity (but the acquired signal will be different because the unit cannot record the lowest frequencies that the EOG100C records even when the latter is high pass filtered).
