Our take on the KLEIN TOOLS Electrical Test Kit MM320

A two-piece electrical test kit from Klein Tools: the MM320 digital multimeter and the NCVT-3P non-contact voltage tester with a built-in flashlight. The kit pairs a general-purpose meter with a pen-style voltage detector, so you can check for live wires before touching them and then measure voltage, resistance and continuity. It suits homeowners, DIYers and apprentices who want one box for basic electrical checks. Against buying the two tools separately, the kit adds convenience and includes the batteries; against pro-grade meters, the MM320 is a simpler, more limited instrument.
