Oscilloscope probes connect compatible oscilloscopes to electrical equipment, taking measurement between two voltage points.

Insulated oscilloscope probe kits connect compatible oscilloscopes to electrical equipment, taking measurement between two voltage points. They also feature one or more removable covers to protect the probe tip.

Retractable terminal block probe sets connect to clamp or screw-type terminal blocks to facilitate oscilloscope measurement in volts. These probes protract like a needle from a syringe when pressure is applied to the finger rest. This allows the unused section of the probe tip to remain covered by the insulation while the usable portion is engaged in the terminal.
