Features: *Made of high-quality materials, *High electromagnetic frequency: The electromagnetic frequency of the generator is 150MHz, and high-efficiency light bulbs can be lit without power supply. * ABS housing: The ABS shell of the pulse generator has excellent for flame retardant and insulation, so you don't have to worry about safety. *Easy charging: 3 holes are charged separately, and each hole takes about 30 minutes to charge. When the indicator of the charger is turned off, it means it is fully charged. *Easy to operate: When the instrument is close to the light-emitting tube part of the lamp, the light will turn on, indicating that the instrument is good and relevant tests can be carried out. *Wide range of uses: High-frequency strong magnetic generators can be used in electronic factories, laboratories, electronic research and development and other factories to test the anti-interference test of electronic motherboard experiments.
