紫(zi)(zi)(zi)外(wai)線(xian)(xian)燈(deng)使用過程中其輻(fu)射強度(du)會逐漸降低(di),應定期(qi)使用專(zhuan)業(ye)的紫(zi)(zi)(zi)外(wai)線(xian)(xian)輻(fu)射照度(du)計對(dui)紫(zi)(zi)(zi)外(wai)線(xian)(xian)殺菌(jun)(jun)燈(deng)進(jin)(jin)行輻(fu)照劑量檢(jian)測,當殺菌(jun)(jun)燈(deng)紫(zi)(zi)(zi)外(wai)輻(fu)照強度(du)≥70uW/cm2時,應對(dui)燈(deng)管進(jin)(jin)行更(geng)換。一般情況下,紫(zi)(zi)(zi)外(wai)線(xian)(xian)燈(deng)管建議8000h后(hou)進(jin)(jin)行更(geng)換,LONGPRO朗普(pu)紫(zi)(zi)(zi)外(wai)線(xian)(xian)燈(deng)管質保(bao)9000h,專(zhuan)業(ye)配(pei)套,紫(zi)(zi)(zi)外(wai)線(xian)(xian)強度(du)高,長壽命,低(di)故障(zhang)。
