He aha ka helu ʻana o micron?

ʻO kahi ana o ka nui o ka pore i loko o ka media kānana. Hōʻike ʻia ma ke ʻano he 'Nominal' a i ʻole 'Absolute'. Nominal Rating pili i ka pākēneka o nā ʻāpana i ka nui i hāʻawi ʻia i hiki i kahi kānana ke hopu ie. ʻO 10 microns ma 90% ʻo ia ka mea e wehe i 90% o nā ʻāpana 10 microns i ka nui. ʻO Absolute e pili ana i ka wehe ʻana i nā ʻāpana āpau i ka nui micron i hāʻawi ʻia a ʻoi aku ka nui. ʻO 20 micron absolute ʻo ia ka 100% o nā ʻāpana 20 microns a i ʻole e hopu ʻia.

ʻO ka haʻahaʻa o ka helu micron, ʻoi aku ka nui o ka pono a no laila ka nui o ka lepo i hopu ʻia.

ʻO ka helu ʻaila kānana micron maʻamau ma kahi o 30. (ʻO ka lauoho kanaka ma kahi o 70 microns)

I ka hoʻohālikelike ʻana i nā ʻano kānana like ʻole micron rating, pono ʻoe e hōʻoia i nā kaʻina hana hoʻāʻo like.
