# PicoAmmeters

Picoammeters measure very low electric current (pico amps) and are used for extremely sensitive measurements. These meters are used when measuring low currents often demands a lot more than a digital multimeter (DMM) can deliver. Generally, DMMs lack the sensitivity required to measure currents less than 100nA. Even at higher currents, a DMM’s input voltage drop (voltage burden) of hundreds of millivolts can make accurate current measurements impossible.
