(3) ☆ Sensitivity level: with low sensitivity, normal sensitivity, high sensitivity and ultra-high sensitivity four-speed switching, no need for periodic adjustment;
(4) Alarm mode: visual light alarm and audible alarm prompt, visual light alarm and vibration alarm prompt;
(5) ☆ The radiation magnetic field emitted by the detector shall not exceed 1.2μT at any point on its surface;
(6) The detector should be able to automatically recover its detection performance within 1mi after leaving the metal object;
(7) Power supply: 9V dry battery or 9V nickel metal hydride battery;
(8) ☆ Battery standby time: long standby time, standby time ≥ 100 hours;
(9) Alarm sound: The alarm sound should be different from the sound that prompts other information. The maximum sound intensity of the alarm sound should not be lower than 75dB;
(10) Alarm display: The alarm display should be different from the non-alarm display. The alarm display light is red, and can be clearly seen in the bright environment of 10000lx and the dark environment of 25lx;
(11) Specification size is not less than: 440mm (length) × 78mm (width) × 50mm (height);
