Monophasic Action Potential Module for Physiology Lab

Module designed for capturing and amplifying monophasic action potentials (MAPs). It incorporates isolated input amplifiers to minimize hum interference by electrically isolating the inputs from the output circuits and housing. Amplified MAP signals can be connected to the system bus for direct recording or computer-based data acquisition. A 10 mV square-wave calibration generator is incorporated for amplitude calibration. A separate connection box is required for connecting MAP electrodes, with individual channel switch-off facilities. Manufactured by Atico Export with a focus on precision, durability and consistent performance for physiological research and experimental laboratory use.
