A heavy-duty electrical tester is a type of electrical tester that is designed to be more durable and withstand more rigorous use than standard electrical testers. They are commonly used in industrial or commercial settings where electrical systems may be more complex or require higher voltage or current levels.
There are several types of heavy-duty electrical testers available, including voltage testers, continuity testers, circuit testers, and multimeters. Some heavy-duty testers may also be designed for specific applications, such as testing high-voltage electrical systems or motor windings.
Heavy-duty electrical testers are designed to be more rugged and durable than standard electrical testers, making them better suited for use in harsh or demanding environments. They may also have additional features, such as higher voltage or current capacity or the ability to measure more complex electrical parameters.
