Sperry Instruments VD7504GFI DualCheck 2-in-1 Voltage Detector GFCI Analyzer

SKU CH-25SF-10R2B

Combines a non-contact voltage detector and GFCI outlet analyzer in one tool with 360° visual and audible alerts for 50–600V AC circuits

  • Two testers in one tool save time and money
  • Non-contact voltage detector senses 50-600V AC at 50-60Hz
  • 360° visual and audible alerts show live voltage instantly
  • Hi-impact housing survives 10 ft drops and 250 lb crush
  • CAT III 1000V rating with C-UL US, CE and OSHA NRTL recognition

Dual-Function Electrical Tester

The Sperry Instruments VD7504GFI combines a non-contact voltage detector and a GFCI outlet circuit analyzer in a single compact tool. It is built for electricians and maintenance technicians who need to verify live conductors and test receptacle wiring without switching devices. The housing uses hi-impact polycarbonate with over-moulded rubber grips and carries a 10 ft drop rating plus a 250 lb crush rating.

Suited for Combined Voltage and Outlet Checks

This unit fits professionals who want both AC voltage detection from 50 to 600 V at 50 to 60 Hz and ground-fault circuit analysis in one hand. The 360° visual LEDs and audible beeper give clear indication from any angle. It is not intended for users who require contact measurement, continuity testing, or voltage readings outside the stated AC range.

Integrated Design Eliminates Extra Tester

Merging the two functions removes the need to carry a separate non-contact detector and a separate GFCI analyzer, reducing tool-belt weight and the chance of leaving one behind. The CAT III 1000 V rating with C-UL US, CE marking and OSHA-recognised NRTL listing confirms the combined circuitry meets recognised safety standards for the stated applications.

Questions about this item

Does the GFCI outlet analyzer require a live AC receptacle to function?

Yes, the GFCI outlet circuit analyzer plugs into a standard receptacle and checks wiring faults on energized circuits.

Will the non-contact voltage detector sense voltage on conductors powered by legacy 60 Hz systems?

Yes, the non-contact detector is specified for 50-600V AC at 50-60 Hz, covering older 60 Hz installations.

How do I confirm the tester is operating correctly before each use?

The 360° visual indicator and audible beep activate when the non-contact tip detects voltage, providing immediate functional verification.
