Safer than solenoid testers and fully compliant with NFPA 70E, (when used properly per Article 110.4 Use of Equipment (A) Test Instruments and Equipment), the T+Pro helps electricians and technicians work safer by indicating the presence of voltage, even when the batteries are dead. Additional functionality, such as a GFCI trip, easy to read LCD screen, resistance measurement up to 9.99 kΩ, and a built-in flashlight make the T+Pro the first voltage tester that electricians reach for.
