If you are a professional electrician, your job demands from you to check a considerable variety of electrical circuitry. Circuit testers are specifically created with the aforementioned purpose in mind. If you don’t own any of these instruments yet, then the market is here to help. Some of these useful tools are created to perform only a single function, however, the majority of them are multifunctional devices specifically designed to perform different kinds of electrical testing. The instruments are utilized to check DC and AC voltage, amperage, short and open circuits, continuity, polarity, and so on.
Such tools work with a wide range of voltages, beginning with 0 and ending with 300 Volts. Also, they can measure resistance. Such articles come with easy-to-read digital screens which display all the information in a clear and concise manner. Our testers are offered in water- and dust-proof cases, with batteries that can last for hundreds of hours on end. Their operating temperature ranges from 14°F to +120°F approximately. Having compact dimensions and light weight, our tools are easy to transport and use. Circuit testers that we carry will come in real handy regardless of whether you are a physics student or an auto mechanic, hence you can shop with confidence!
