Sperry Instruments STK001 Voltage & GFCI Tester Kit

SKU CH-12S5-99M8B

A non-contact voltage tester and GFCI outlet tester kit that detects 50-1000V AC with audible and 360° visual alerts, checks seven wiring conditions, and withstands 10 ft drops and 250 lb crush

  • Non-contact detection of 50–1000 V AC with audible and 360° visual alerts
  • Patented battery self-test prevents false negatives on the voltage tester
  • Seven wiring-condition checks at the press of a button on the GFCI tester
  • CAT III 300 V and CAT III 1000 V / CAT IV 600 V safety ratings
  • Impact-resistant ABS housing survives 10 ft drops and 250 lb crush force

Kit contents and intended users

The kit combines a non-contact voltage tester and a GFCI receptacle tester for electricians, inspectors, technicians and homeowners who need to confirm AC voltage presence and verify outlet wiring before starting work. Both tools feature high-impact ABS housings with over-moulded rubber grips for a compact, ergonomic feel during repeated use.

Replaces separate purchases

Buying the pair together removes the need to source a voltage detector and an outlet analyser individually. The voltage tester includes a patented battery self-test that checks the unit and its cells before each use, virtually eliminating false-negative readings when confirming circuits are dead.

CAT ratings and physical limits define safe

The voltage tester carries CAT III 1000 V and CAT IV 600 V ratings with 50–1000 V AC detection, while the receptacle tester is rated CAT III 300 V. Both units survive a 10 ft drop and a 250 lb crush test. The receptacle tester reads seven wiring conditions through colour-coded neon lights, and the voltage tester provides 360° visual and audible alerts.
