Hand-held metal detectors are often used to detect metal objects carried by people or objects. It can detect weapons, explosives or small pieces of metal in packages, luggage, letters, fabrics, etc. carried by people. The special appearance of its sensitive appearance makes it easy to operate. Better than ring sensor probes. Ultra-high sensitivity, special application. Such as prisons, chip factories, archaeological research hospitals, etc. The hand-held security metal detector is used to check the specific location of the metal carried by the person, and can also be used in conjunction with the metal detection door. When the "security door" alarms and finds metal objects, the handheld metal detector can be used to find the metal objects hidden exact location. The metal detector uses a rectangular detection head, and the detection area is 12 cm long. When examining the human body, the inspection operation is completed from top to bottom at one time.
Sula n-úsáidfear é, ar dtús oscail an clúdach urrann ceallraí ar chúl na hionstraime agus cuir isteach an ceallraí. Úsáideann an ionstraim seo ceallraí lannaithe 9V, tabhair faoi deara go gcaithfidh an voltas ainmniúil ar an gceallraí a bheith 9V, agus ní féidir voltais eile a chur in ionad. Tá tomhaltas cumhachta na hionstraime seo an-íseal, agus is féidir le gach ceallraí nua-shuiteáilte thart ar 50 uair an chloig oibríochta a charnadh. Nuair a thiteann an chumhacht ceallraí go 10 faoin gcéad , níl an ionstraim ag obair i gceart a thuilleadh, agus déanfaidh an cainteoir fuaimeanna cliceáil uaireanta, rud a léiríonn go bhfuil sé riachtanach an ceallraí nua a athsholáthar.
