1, the principle is different: the high-frequency hertz instrument uses high-frequency alternating current and oscilloscope tube to observe the movement of electrons and measure the parameters of voltage signal; Intense pulsed light instrument uses intense pulsed light to irradiate the skin, producing thermal effect to achieve therapeutic effect.

2. Different uses: high-frequency hertz instruments are used to measure high-frequency voltage signals, and are used for measurement and analysis in the fields of electronics, communication and radio; Intense pulsed light instrument is used for depilation, treatment of acne, vascular diseases and reduction of pigmentation.
