Product Description
-
Txais cov cuab yeej ntsuas ultrasonic qib siab kom raug ntsuas, tso saib thiab khaws cov dej ntws los ntawm cov kav dej;
Advanced technologies xws li segmental calibration thiab tsis siv neeg muaj peev xwm taug qab tau txais yuav;
Nws muaj qhov zoo ntawm qhov ntsuas qhov tseeb, ntau qhov sib piv, muaj kev ntseeg tau zoo, thiab lub neej ntev;
Cov qib dej tsis zoo ncav cuag IP68;
Kev ntsuas qhov raug siab, kev tsim kho yooj yim, thiab kev ua haujlwm yooj yim tuaj yeem luam tawm thiab tswj tau los ntawm cov chaw taws teeb, uas yog qhov zoo rau kev tswj xyuas niaj hnub no;
Txhawb nqa ntaiv dej tus nqi kom yooj yim hloov tus nqi dej;
Ntau cov lus nug txheeb cais thiab kev txheeb xyuas cov ntaub ntawv ua haujlwm los pab txhawb kev sau cov ntaub ntawv thiab txheeb cais;
Tsim kom muaj dej tsis zoo, tsim nyog rau sab nraum zoov hauv av, qhov dej hauv av, thiab lwm yam. -
