GAOTek presents a full portfolio of electrical testers that include a wide collection of products such as spectrum analyzers, digital oscilloscopes, digital multimeters, logic analyzers, and generators. Our products offer technicians and field professionals the best performance for a variety of electrical testing applications. Electrical testers are accurate, safe and easy to use. They are designed to check non-contact to contact voltage and continuity detection, circuit problems, open jaw current and motor phase rotation-testing. They also ensure voltages are correct at the electrical panels.

Functions of Electrical Testers

Our spectrum analyzers are electronic test equipments which are used for analysing a system of oscillations, especially sound, into its separate components. We offer a selection of cable & antenna, high performance, and radio frequency spectrum analyzer options.


GAOTek's electrical testers are portable, well constructed and lightweight. Some of the products can run with any operation system such as MAC OS, Linux, and Windows. Also several of them have gas purging input ports / output ports, built-in cut filters, and speed mode options, which increase the sweep speed. Other products have display sections that are equipped with three basic controls, including a focus knob, an intensity knob, and a beam finder button. Additionally, some of these instruments feature an easy-to-read digital LCD display and automatic zero adjust. Logic analyzers have long capture times and also navigate the data easily. They have features such as debugging source code, and built-in decoding.

Applications and Industries

GAO Tek’s electrical testers are widely used in many industries such as telecommunications, consumer electronics, healthcare, life science/medical research, security, sensing, microscopy, and gas/chemical analysis, environmental monitoring, engineering, and automotive.
