HD-PA7 Series

A slightly larger version of the HD-PA6 series, with a heavier spring force. This range of test probes can be used for load and functional testing of power components such as semiconductors, solenoids, loaded PCBs, bus-bars, wound components and batteries. They share identical dimensions and will readily intermix with the PA7 series general purpose test probes.
