Features: High-tech electronic product Electronic insect repeller is a new type of high-tech electronic product, which uses high-frequency ultrasonic circuit to generate 20~55KHZ scanning ultrasonic waves. Scientific research has shown that mosquitoes, cockroaches, mice, mites and other pests in the sound wave range of this frequency , their endocrine system and physiological functions will produce flocculation, thus playing a motor role, ultrasonic has no effect on the human body and other animals Harmful, because more than 20KHZ sound waves can not be heard.< /p> Ultrasonic Wave Variable frequency ultrasonic waves and other technologies have been used to hunt various pests within the jurisdiction. Microcomputer chips and electronic integrated circuits are used. Small and exquisite appearance, easy to operate. High quality The ultra-low frequency electromagnetic wave emitted by this product can penetrate the wall effectively and will not reduce the use effect due to blocking by
