DRK506 PFE tester rau pellet pom kev ua haujlwm ntawm daim npog ntsej muag

[Introduction]

Kev kho mob daim npog ntsej muag particle filtration efficiency PFE tester yog tsim rau cov cuab yeej tshuaj xyuas chaw kuaj mob, chaw soj ntsuam kev nyab xeeb, chaw kuaj xyuas kev ua haujlwm, chaw tshuaj xyuas tshuaj, chaw tiv thaiv kab mob thiab tswj chaw, chaw soj ntsuam textile, tsev kho mob, daim npog qhov ncauj thiab lub tshuab ua pa, thiab lwm yam.

PFE tester rau particle filtration efficiency ntawm phais qhov ncauj qhov ntswg yog txawm peem rau nrog ib tug tshwj xeeb ntsev aerosol generator, uas muaj peev xwm tsim aerosols nrog ib tug particle loj thiab concentration.

Nruab nrog ib tug series ntawm tshwj xeeb fixture, haum rau nrhiav kom tau ntawm txhua yam ntawm lub qhov ncauj qhov ntswg.

Built-in lub neej siab photometer module, piv txwv lub sij hawm tsub zuj zuj, kom lub teeb tu.

Tsis siv neeg tswj ntawm aerosol tiam, tsis siv neeg suav ntawm kev ntes efficiency thiab daim npog qhov ncauj airflow kuj, txo tib neeg kev cuam tshuam.

Ua-nyob rau hauv high precision hluav taws xob flowmeter thiab kev ua haujlwm siab sampling twj tso kua mis los xyuas kom meej txaus stability.
