Peb feem ntau pom cov qauv kev tiv thaiv xws li IP55, IP68, thiab IPX7. Yog li cov no txhais li cas?
Siv IP55 ua piv txwv, IP sawv cev rau kev tiv thaiv, thiab qib 55 sawv cev rau qib. Thawj tus lej yog qib ntawm cov khoom siv tshuaj tiv thaiv, thiab tus lej thib ob yog qib ntawm cov kua tshuaj tiv thaiv, uas txhais tau tias qib 5 plua plav thiab dej tsis kam. Raws li rau lub ntsiab lus ntawm X thiab sawv cev tsis muaj dab tsi, piv txwv li, IPX7 tsuas yog sawv cev rau qib 7 waterproofing.
