Klein Tools Digital Multimeter Premium Electrical Test Kit

SKU CH-FKK6-2D4EJ

Complete electrical test kit includes a digital multimeter measuring 600 V and 10 A, a dual-range non-contact voltage tester from 12 to 1000 V, and a GFCI receptacle tester with backlit LCD readout

  • TypeMultimeter Accessories
  • Complete kit includes multimeter, voltage tester and receptacle tester
  • Multimeter MM320 measures up to 600V AC/DC voltage and 10A DC current
  • NCVT3P detects 12 to 1000 VAC and 70 to 1000 VAC ranges
  • RT250 shows voltage on backlit LCD and detects Open Neutral and Open Ground faults
  • GFCI trip-time test verifies breaker function on 120V North American outlets

Complete Electrical Test Kit

This kit bundles a digital multimeter, a non-contact voltage tester with flashlight, and a GFCI receptacle tester for electrical test and measurement tasks. It suits electricians, technicians and DIY users who need voltage, current, resistance, battery, diode and continuity checks in one package. The multimeter measures up to 600V AC/DC voltage, 10A DC current and 2MOhms resistance.

Verify Outlet Compatibility First

The receptacle tester is designed for 3-wire, North American 120V outlets only and will not function on other voltages or wiring systems. Confirm that your test environment uses this outlet type before ordering. The non-contact voltage tester operates in dual ranges from 12 to 1000 VAC or 70 to 1000 VAC for low-voltage and standard applications.

Replaces Separate Tool Purchases

Buyers who currently carry individual meters, voltage pens and outlet testers can consolidate them into this single kit. The jump is worth it when you want coordinated tools that cover multimeter functions, non-contact detection up to 1000 VAC and GFCI trip-time verification with backlit LCD readout. It is not for users who need higher current ranges or non-North-American outlet testing.
