Pha-1701 portableKua Meteryog digital zaubKua Meter, nrog LCD Drops zaub, uas tuaj yeem tso tawmPHthiab ntsuas kub ib txhij. Qhov ntsuas tau rau cov labs hauv cov tsev kawm qib siab hauv tsev kawm qib siab, kev tshawb fawb, kev lag luam lossis lwm cov chaw ua haujlwm los txiav txim siab cov kev daws teeb meem aqueous 'PHQhov tseem ceeb thiab muaj peev xwm (MV) qhov tseem ceeb. Nruab nrog Orp electrode, nws tuaj yeem ntsuas kev daws teeb meem thiab kev daws teeb meem oxidation); Nruab nrog cov ion tshwj xeeb electrode, nws tuaj yeem ntsuas lub electrode tej yam muaj peev xwm ntawm electrode.

Dab tsi yog ph?
PH yog kev ntsuas ntawm hydrogen ion kev ua hauv kev daws teeb meem. Dej ntshiab uas muaj kev sib npaug sib npaug ntawm hydrogen ions (h +) thiab
tsis zooHydroxide ions (Oh -) muaj qhov nruab nrab pH.
● Cov kev daws teeb meem nrog lub siab dua ntawm hydrogen ions (h +) dua li dej ntshiab yog acidic thiab muaj cov pheeb tsawg dua 7.
● Cov kev daws teeb meem nrog kev xav tau ntau dua ntawm hydroxide ions (Oh -) dua li dej yog qhov yooj yim (Alkaline) thiab muaj lub ph loj dua 7.
