±25V Voltage logger sensor NUL-251

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.

ORP logger sensor NUL-258

The NeuLog ORP (Oxidation Reduction Potential) sensor can be used to quantify whether a substance is a strong oxidizing agent or a strong reducing agent. For example, the ORP electrodes are used to measure the oxidizing ability of chlorine in swimming pools.

The electrode has two components: a measuring half-cell comprised of platinum metal immersed in the solution in which the redox reaction is taking place, and a reference half-cell (sealed gel-filled Ag/AgCl) to which the platinum half-cell is referenced.
