With the enhancement of people's awareness of safety, a non-contact electric test pen has been derived; the induction electric test pen is a common electrical tool and one of the necessary tools in the electrical industry. It does not require any physical contact, adopts the principle of electromagnetic induction, and can measure the current and voltage in the circuit on the south side of the street; it is suitable for measuring whether the primary circuit or secondary circuit of low voltage is charged, detecting line faults, and protecting the safety of electricians. The equipment has the characteristics of being fast, convenient, and accurate, not only widely used in the electrician industry, but also welcomed by family DIY. With the development of technology, the induction test pen is constantly updated, the performance is continuously improved, and the use is more convenient. At the same time, the continuous development of the electrical industry also drives the development of the induction measuring pen industry. The induction test pen industry will provide more efficient and accurate services for the electrical industry.
