Cov lus qhia tshwj xeeb rau ultraviolet irradiance meters
Ultraviolet irradiance meter yog ib qho cuab yeej uas ntsuas qhov kev siv ntawm ultraviolet hluav taws xob nyob rau hauv lub wavelength ntawm 254nm. Siv tshwj xeeb qhov muag tsis pom lub raj ultraviolet sensor technology, nws tsis cuam tshuam los ntawm lub hnub ci thiab lwm yam kev cuam tshuam hluav taws xob, muaj qhov ntsuas qhov tseeb, thiab kev ua haujlwm ruaj khov. Nruab nrog tsis siv neeg roj teeb undervoltage qhia thiab cov ntaub ntawv khaws cia muaj nuj nqi.
piav qhia luv luv
Lub digital ultraviolet irradiance meter yog ib qho cuab yeej uas ntsuas qhov kev siv ntawm ultraviolet hluav taws xob ntawm lub wavelength ntawm 253.7nm. Siv tshwj xeeb qhov muag tsis pom lub raj ultraviolet sensor thev naus laus zis, nws tsis cuam tshuam los ntawm tshav ntuj, lub teeb, thiab lwm yam cuam tshuam hluav taws xob, muaj qhov ntsuas qhov tseeb, thiab kev ua haujlwm ruaj khov. Nruab nrog tsis siv neeg roj teeb undervoltage qhia thiab cov ntaub ntawv khaws cia muaj nuj nqi. Tag nrho cov tsim yog compact thiab yooj yim heev rau siv. Haum rau kev saib xyuas cov hluav taws xob siv hluav taws xob ntawm cov teeb ci ultraviolet hauv tsev kho mob, chaw saib xyuas kev noj qab haus huv thiab kev tiv thaiv kab mob sib kis, tshuaj lom neeg, hluav taws xob, khoom noj khoom haus, chaw lom zem, thiab lwm yam.
Cov neeg siv phau ntawv no suav nrog cov ntaub ntawv ntsig txog kev nyab xeeb thiab ceeb toom ceeb toom. Thov nyeem cov ntsiab lus tseem ceeb thiab ua raws li tag nrho cov lus ceeb toom thiab ceev faj.
