Schumann Wave Generator 0.01Hz–100KHz Pure Sine Signal

Etmakit Schumann Wave Generator | Pure Sine Frequency Modulation Signal Generator

Experience the calming resonance of Earth's natural electromagnetic frequency with the Etmakit Schumann Wave Generator. This professional-grade, ultra-low frequency signal generator outputs a pure sine wave defaulting to the iconic 7.83Hz Schumann resonance frequency — the same natural frequency found in Earth's electromagnetic field. Whether you're setting up a home sanctuary, a meditation studio, a sleep-friendly bedroom, or a laboratory workbench, this compact and highly integrated device covers a remarkably wide frequency range of 0.1Hz to 100,000Hz.

With its digital circuit design, transparent acrylic housing, and simple button interface, this generator is equally suited for electronics hobbyists, wellness enthusiasts, and professional researchers. Made in Mainland China.
