1. Product introduction:
It is a miniaturized non-linear node detector that can detect electronic devices hidden in walls, floors, ceilings, lamps, furniture, or containers, regardless of whether these electronic devices are transmitting signals, turning on or off, and displaying, Various methods such as sound and vibration are used to alert, so that the detection personnel can find the target device, and protect the privacy of the organization and individual.

2. Main features:
1. Strong semiconductor recognition ability: Built-in spectrum analyzer that supports second and third harmonic detection can quickly and effectively identify semiconductor devices and equipment
2. High sensitivity: Built-in high-gain antenna, large detection distance, especially for SIM card equipment, has a high sensitivity, to ensure that secret records, mobile phone communication equipment can be quickly detected
3. Low false alarm rate: The built-in non-destructive detection algorithm greatly improves the detection ability, and the false alarm rate is extremely low
4. Safe and reliable: the characteristics of the equipment meet the requirements of electromagnetic radiation, and it is absolutely safe for the human body
5. Flexible operation: small size, flexible operation, simple and practical, and good user experience
6. Cost-effective: the world‘s most cost-effective, cost-saving and excellent performance
