Qhov sib thooj hloov pauv yog ib yam ntawm cov khoom muaj peev xwm "sensitive" ze rau nws cov khoom, nws yog qhov hloov pauv hloov pauv, uas tuaj yeem siv cov yam ntxwv ntawm qhov hloov pauv hloov pauv kom nkag siab rau cov khoom txav mus los, kom ua tiav lub hom phiaj ntawm tswj qhov hloov pauv kom qhib lossis kaw, los ntawm ib qho khoom mus rau qhov hloov pauv thiab qhov kev nkag siab ntawm kev txav mus los ntawm qee qhov kev ncua deb, qhov kev ncua deb no yog hu ua qhov deb ntawm qhov ntsuas los ntawm kev txav chaw. Qee lub sij hawm cov khoom yuav raug kuaj pom mus rau qhov hloov mus tas li ntawm qee lub sijhawm thiab tom qab ntawd tawm mus tsis tu ncua, uas yog rov ua dua. Cov sib txawv sib txawv sib txawv muaj peev xwm teb sib txawv rau cov khoom raug ntsuas, uas yog hu ua cov lus teb zaus.
(1) Thaum cov khoom ntsuas yog cov hlau tsis muaj hlau, nws yuav hnov mob txawm tias qhov ntsuas qhov deb me me heev. Tsis tas li ntawd, nyias txheej yog undetectable.
(2) Lub sijhawm kaw ntawm qhov hloov pauv inductive sib thooj yog 50ms, yog li thaum siv cov khoom no, tus neeg siv yuav tsum xub qhib lub hwj chim ntawm qhov sib thooj hloov, vim tias lub zog siv los ntawm kev thauj khoom thiab qhov sib thooj sib txawv.
(3) Tsis txhob siv qhov sib thooj hloov hauv DC magnetic teb saum toj 200 gauss kom tsis txhob ua haujlwm tsis raug.
(4) Tsis txhob tso qhov sib thooj mus rau hauv cov tshuaj hnyav, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj zog acid thiab alkali.
