Testo 0590 7503 750-3 - Digital Voltage Tester with GFCI Test


The 750-3 can perform GFCI Circuit tests on AC outlets. When performing a GFCI circuit test, a 35 mA load is applied to the circuit. The testo 750 vibrates ensuring that the GFCI circuit test is active. In addition to the above features, the testo 750-3 includes a 3-digit LCD showing the actual voltage measurements.

The testo 750 voltage testers are the first instruments to include an all-around viewable LED voltage indication. All three models include low input impedance, phase sequence, continuity test, and meet CAT III 1000 V CAT IV 600 V safety standards.

  • GFCI Test Function
  • 3-digit LCD showing the actual voltage
  • measurements
  • Patented all-around viewable LED voltage bar indication
  • Built-in flashlight for testing in dark places
