0.001Hz-200KHz 7.83HZ Schumann Audio Resonator UltraLow Frequency PulseWave

Features:
Using fine quality materials, the frequency stability of the product is fine.
This product can not only output 7.83Hz SchumannWave, but also adds programmable frequency modulation technology, which can adjust the frequency within the range of 0.001Hz-200KHz.
Professional oscilloscope measuremen, 7.83Hz standard sinewave, Waveform is real and effective.
Digital circuit crystal oscillator frequency reference, more stable and strong anti-interference.
The powersupply interface adopts DC5.5*2.1 interface, which is easy to use, and the USB can be plugged into the powerbanks or USB charginghead or other USB powersupply equipment to work.
