The voltammeter / amperometer module VA-10M is a sensitive (picoampere range) current amplifier that is intended for voltammetric and amperometric measurements with carbon-fiber microelectrodes in biological systems, where the total currents do not exceed 100 nA.
The VA-10M EPMS module has the same specification as the
VA-10X 19" stand-alone device except that it has other filter (2-pole Bessel FILTER, corner frequencies: 100, 300, 500, 1k, 3k and 5k Hz) and gain (x0.5, x1, x2, x5, x10, x25 mV/pA) settings.
