Mfundo Yoyambira ya pH Electrode
Mu muyeso wa PH, njira yogwiritsira ntchitoelekitirodi ya pHimadziwikanso kuti batire yoyamba. Batire yoyamba ndi dongosolo, lomwe ntchito yake ndi kusamutsa mphamvu ya mankhwala kukhala mphamvu yamagetsi. Mphamvu ya batire imatchedwa mphamvu yamagetsi (electromotive force). Mphamvu yamagetsi iyi (EMF) imapangidwa ndi mabatire awiri a theka. Batire imodzi ya theka imatchedwa electrode yoyezera, ndipo mphamvu yake imakhudzana ndi ntchito yeniyeni ya ma ion; batire ina ya theka ndi batire yoyezera, yomwe nthawi zambiri imatchedwa electrode yoyezera, yomwe nthawi zambiri imalumikizidwa ndi yankho loyezera, ndipo imalumikizidwa ku chida choyezera.
Mawonekedwe
1. Imagwiritsa ntchito dielectric yolimba yapadziko lonse lapansi komanso malo ambiri a PTFE amadzimadzi kuti agwirizane, ovuta kutsekeka komanso osavuta kusamalira.
2. Njira yofalitsira ma electrode kutali imakulitsa kwambiri moyo wa ntchito ya ma electrode m'malo ovuta.
3. Palibe chifukwa chowonjezera dielectric ndipo pali kukonza pang'ono.
4. Kulondola kwambiri, kuyankha mwachangu komanso kubwerezabwereza bwino.

N’chifukwa chiyani muyenera kuyang’anira pH ya madzi?
Kuyeza pH ndi gawo lofunika kwambiri pa njira zambiri zoyesera ndi kuyeretsa madzi:
● Kusintha kwa pH ya madzi kungapangitse kuti mankhwala m'madzi asinthe.
● pH imakhudza ubwino wa chinthu komanso chitetezo cha ogula. Kusintha kwa pH kungasinthe kukoma, mtundu, nthawi yosungiramo zinthu, kukhazikika kwa chinthu komanso asidi.
● Kusakwanira pH ya madzi apampopi kungayambitse dzimbiri mu dongosolo logawa madzi ndipo kungapangitse kuti zitsulo zolemera zoopsa zituluke.
● Kusamalira malo okhala ndi pH ya madzi m'mafakitale kumathandiza kupewa dzimbiri ndi kuwonongeka kwa zipangizo.
● M'malo achilengedwe, pH ingakhudze zomera ndi nyama.
