Electrical Testers
GAO’s electrical testers are devices used to measure, test, and troubleshoot electrical parameters and conditions in electrical systems and circuits. They are used by electricians, technicians, and professionals working with electrical equipment. Our electrical testers come in various forms, each designed for specific testing purposes.  

GAO’s electrical testers are composed of display probe or test leads, measurement range selector, power source, control buttons, sensors, circuit protection, housing, calibration adjustments, data logging or connectivity. 

The other common names of the other electrical testers are voltage testers, continuity testers, multimeters, ammeters, ohmmeters, insulation testers, phase sequence testers, clamp meters, ground testers, power quality analyzers, frequency counters, earth resistance testers, impedance analyzers, network analyzers, surge testers, high-potential testers, leakage current testers, power factor meters, capacitance meters, inductance meters, function generators, logic analyzers, oscilloscope, EMI/RFI testers, battery testers, field intensity meter, cable testers, spectrum analyzers, dielectric strength tester, and infrared thermometers. 

GAO Tek has been focused on servicing the North American markets and has earned praise from many of its customers in the U.S., Canada, and Mexico.

This includes voltage fluctuations, harmonics, power factor, voltage/current waveform distortions, and other power-related anomalies. Our power quality analyzers help in diagnosing power quality issues, assessing system performance, and identifying potential electrical problems.
  • Continuity Tester: GAO Tek continuity testers are used to check the continuity of electrical connections, wires, and components. They help in determining if a circuit is complete (closed) or broken (open). GAO continuity testers are used during installation, troubleshooting, or repair to ensure proper circuit connectivity and identify any interruptions or faults.
  • Phase Rotation Tester: Our phase rotation testers are used to determine the rotation direction of three-phase electrical systems. They help ensure that all phases are correctly connected and aligned, preventing potential equipment damage or operational issues due to incorrect phase rotation.
  • Ground Resistance Tester: Our ground resistance testers are used to measure the resistance of the grounding system. They help in evaluating the effectiveness of grounding and bonding in electrical installations, ensuring compliance with safety standards and minimizing the risk of electrical hazards.
