PK3 Series

A range of concentric test probes intended specifically for making 4 to 6 pole (Kelvin) tests on PCBs, bus bars, equipment chassis and screw heads. A wide range of tip styles is available including sharp inner and outer probes for contact problem areas and concaved outer designed for contacting pan-head screws. This range makes low resistance measurements very easy. Contact us regarding our high current/heavy duty range.
