+/- 25V Voltage logger sensor NUL-251

±25V Voltage logger sensor


This sensor measures voltages across various resistive, capacitive and inductive components, as well as those of photovoltaic cells, batteries and power supplies. This sensor can also be used to measure electrode potentials and to investigate the charging and discharging of capacitors.

When used in conjunction with the Current sensor, the dependence of the current flowing on the applied voltage can be studied in various electric circuits.

This sensor can be used to measure low voltage AC and DC circuits. With its 4 mm plugs, it can easily be connected into electric circuits.
