Feature:1. Antieavesdropping detectors use the principle of radio detection to detect closet eavesdropping devices.2. With 1MHZ8000MHZ high frequency range, has wide application range, strong practicability.3. The shell is made of ABS material, which is light and wearresistant, and is not easy to corrode after longterm use.4. Onepiece design, which has glossy appearance without burrs, more stable installation and use.5. With probe and antenna, the signal response is very sensitive, you can quickly find the source of the bug.Specification:Item Type: DetectorMaterial: ABSModel: K18Frequency Range: 1MHZ-8000MHZAdapter: US plug 100-240VDetection Dynamic Range: >73DBDetection Sensitivity: 0.03mv (main frequency band)Detection Range: 2.4G: 10 (standard 10mw), 1.2G: 15 (standard 10mw), mobile phone frequency band 2G/3G/4G: 15Features: 10-level digital tube, buzzer, vibrator indicationBattery Model: Lithium batteryBattery Capacity: 1000mA (built-in battery)Full Charge Time: 3 hoursWorking Current: 60-110mAContinuous Working Time: 4-5 hours.Package List:1 x Host1 x Probe1 x Adapter1 x Antenna1 x User Manual
