Indlela ukukhetha isizinda, kuncike imigomo?

On isihloko kanjani ukukhetha umtshina, kulotshiwe eningi izihloko. Kodwa iningi labo yokukhangisa ngokwemvelo, orienting umfundi ukuthenga lolutsite. Thina ngeke kuthinte brand lesitsite, kodwa umane ukusiza eyolanda metal detector, kuye ngokuthi imigomo yakho.

Kuyaqhubeka ukuthungathwa amanzi

Lapha esinazo emqondweni nje yokusesha ikhoyili phansi emanzini yehle ne unit emfuleni noma phansi kolwandle. Lezi imitshina metal luvikelwe ngokuphelele kusukela umswakama: kanye headphones, kanye nezindlu. Ngo o uhle ezifana, headphones ziyingxenye ebalulekile zedivayisi, njengoba kwamanzi metal detector kungukuthi ifakwe ukubonisa futhi kuhlinzeke imininingwane ngokufinyelela yomsindo kuphela. izilungiselelo lisebenze Ngenxa kungenziwa ukuseshwa kwabezindaba ehlukahlukene (ngezansi, okunosawoti futhi amanzi ahlanzekile, esogwini) kuhlanganise lenguquko ethize kunhlobonhlobo zamatshe amanzi hhayi kuphela, kodwa futhi izinhlobo ezahlukene ukuphazamiseka.

Ngaphambi ukhetha metal detector ukusesha ezijulile, kufanele uhlole ibhajethi yakho, ngoba lezi zinto eshibhe aqala ku- $ 1000. Lezi amadivayisi zenzelwe ukucinga izinto ezinkulu metal ekujuleni ka-6 wamamitha ubude. Futhi emikhulu into, kujula ke uzothola metal detector. Kuyaphawuleka ukuthi nakuba lezi amadivaysi futhi babe nozwela efanayo okusezingeni eliphezulu, kanye eminye imitshina metal (arched, phansi, njll ..), Kodwa omunye uhlamvu lwemali bathola zimane ayikwazi ukwenza. Kodwa uma siyigugu (zemali ukuminyana), ipayipi noma mgodi, sicela. Lezi amadivayisi esinye isici eyinqaba: banayo cishe akukho ukubandlulula. Okungukuthi, ukuze sihlonze igugu itholiwe, kumele sisuswe. Futhi ekugcineni, tip for labo abafuna ulondoloze imali ukuthenga umtshina ezijulile-amanzi. Ezinye izinkampani i-ezivamile ngwenya metal detector ukukhiqiza ekhethekile umlomo wombhobho ezijulile-amanzi, okwandisa angamamitha angu-1.5 ukujula, kanye nezinto ezihlukahlukene imisebenzi nokusesha ubuchwepheshe. Noma kunjalo, le ndlela ayenzi idivayisi a we metal detector ukujula eligcwele, kodwa abonise ukusebenza yayo kuphela. Kodwa ungase ucabangele le ndlela ne etheni.

igolide Ukucinga

Asikho isidingo ucabange indlela ukukhetha i-metal detector singesegolide, ngoba le njongo kukhona onobuhle ekhethekile ngozwelo eliphezulu kakhulu. Amadivayisi anjalo ziyakwazi ukuthola ngisho izinhlayiya ezincane kunazo egolide. Isimiso ezisebenza we umtshina yalolu hlobo silula. Njengoba igolide has a conductivity ethize kagesi, abakhiqizi walala ekuqaleni e imvamisa iyunithi elihambisana ngomthamo usuwonke lokhu metal. Yiqiniso, lokhu ukuzwela unika imiphumela emihle yokusesha nezinye izinto.

Uma kukhona umbuzo: "Indlela ukukhetha metal detector ibangana kakhulu '- ke udinga Pinpointers (pin pointer)?. Uma kuhunyushwa igama negama kula izwi ne-English, kuvela "isikhombi amaphuzu." Le divayisi yakhelwe ukucacisa ngqo (kuya milimitha) indawo into at a 5 cm ukujula. Kulesi imodeli, akukho ukubandlulula, futhi ingasetshenziswa ukuthola izinto ezincane (imigexo, izinkinobho, zemali, njll) at emaphethelweni, futhi izindawo zokulahla kuzo zonke izimo lapho akunakwenzeka ukuba uthole into ukutholwa idivayisi ezivamile.
