Complete Professional Electrical Diagnostics with High-Precision Premium Testers

The Klein Tools 69355 Premium Electrical Test Kit is an expertly curated collection of diagnostic tools designed for maximum safety, versatility, and accuracy. This kit features the MM320 Manual-Ranging Digital Multimeter, capable of measuring up to 600V AC/DC voltage and 10A DC current, making it perfect for residential and light industrial applications. Whether you are testing batteries, verifying diodes, or checking continuity, the MM320 provides the rugged reliability professional electricians trust.

For non-contact safety, the NCVT3P Dual Range Tester offers an expanded detection range from 12V to 1000V AC, allowing you to identify both low-voltage signals and standard household power. The integrated high-intensity flashlight ensures you can work safely in dark enclosures. Complementing these is the RT250 GFCI Receptacle Tester, which features a large backlit LCD to display real-time voltage and patent-pending detection for complex "Open Neutral/Open Ground" wiring faults. This comprehensive set is the ultimate solution for identifying wiring errors, testing safety devices, and ensuring system integrity.

Key Features

  • Versatile Multimeter: Measures AC/DC voltage up to 600V, 10A DC current, and 2MOhms resistance.
  • Dual-Range Voltage Detection: NCVT3P detects 12V-1000V AC or 70V-1000V AC for broad application coverage.
  • Advanced GFCI Testing: RT250 identifies wiring conditions and displays the exact time required to trip a GFCI device.
