| Experimetria's EXT1 is a low-noise, high input impedance amplifier designed for extracellular applications. It is capable of measuring in-vivo or in-vitro elicited or spontaneous tissue action potentials by means of ECG, EEG, EMG surface or needle electrodes. A pre-amplifier substantially reduces input noise, permitting the use of optimal length cords between the electrode and the coupler, with high input resistance (10 megaohm symmetrical) and low noise (1.5 µV p-p). Amplification is adjustable from 100 to 100,000 using a three-position selector and potentiometer. Filtering is adjustable from 0.5-500 Hz and 0.05-20 kHz with two ten-position selectors. | ||
