Semusayendisiti werabhoritari, chimwe chezvishandiso chakakosha chauchazoda ndeye pH mita. Chishandiso ichi chakakosha pakuona kuti unowana mhinduro dzekuongorora kwemakemikari. Muchikamu chino, tichakurukura kuti pH mita chii, kuti inoshanda sei, uye kukosha kwayo mukuongorora marabhoritari.
Chii chinonzi pH Meter?
A pH metre chinhu chemagetsi chinoshandiswa kuyera pH (acidity kana alkalinity) yemushonga. Iine probe inopinzwa mumhinduro iri kuedzwa, uye mudziyo unoyera kugona kwemagetsi pakati peprobe nereference electrode. Izvi zvinogoneka zvinobva zvashandurwa kuita pH kuverenga.
Iyo pH Meter Inoshanda Sei?
Iyo pH mita inoshanda zvichibva pamusimboti we electrochemistry. Iyo probe ine girazi electrode, iro rakatetepa, rinonzwa girazi membrane rinopindura shanduko muacidity kana alkalinity yemhinduro. Iyo membrane yakaputirwa nechinhu chakakosha chinoburitsa simba remagetsi kana yaiswa kune acidic kana yakakosha mhinduro. Iro referensi ye electrode, kune rumwe rutivi, inopa simba rakagadzikana remagetsi rinoshandiswa sekuenzanisa kune zvinogona kugadzirwa negirazi electrode. Musiyano wekugona kwemagetsi pakati pema electrode maviri woyerwa nepH mita, uye pH kuverenga inoverengerwa.
Kukosha kwe pH Meter muLabhoritari Analysis
Iyo pH mita chishandiso chakakosha mukuongorora marabhoritari, uye inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira:
1. Environmental Testing
Mukuedza kwezvakatipoteredza, pH metres anoshandiswa kuyera pH yevhu, mvura, uye mweya. Ruzivo urwu rwakakosha pakuongorora kunaka kwemhoteredzo uye kuona zvingangobva mukusvibisa.
2. Food and Beverage Testing
Muindasitiri yechikafu nechinwiwa, pH metres inoshandiswa kutarisa acidity kana alkalinity yezvakasiyana zvigadzirwa. Ruzivo urwu rwakakosha mukuona kuti chigadzirwa chakachengeteka kuti chishandiswe uye chinosangana nezvinodiwa nemutemo.
3. Pharmaceutical Analysis
Mukuongorora kwemishonga, pH mamita anoshandiswa kuyera pH yemishonga yemishonga. Idzi ruzivo rwakakosha mukuona kuti mushonga wakadzikama uye unoshanda.
4. Chemical Analysis
Mukuongorora kwemakemikari,pH mamitaanoshandiswa kuyera pH yemhinduro, kusanganisira acids uye mabhesi. Ruzivo urwu rwakakosha pakuona kusanganisirwa kwemhinduro uye kuona chero maitiro anogona kuitika.
Mhando dzepH Meter
Kune marudzi maviri makuru emamita pH: analog uye digital.
Analog pH Mamita
Analog pH metres imhando yechinyakare yemamita pH, uye vanoshandisa tsono nechikero kuratidza pH kuverenga. Mamita aya haadhure pane emamita edhijitari, asi haana kunyatsojeka uye kushoma chaiko.
Digital pH Mamita
Digital pH metres imhando yemazuva ano yepH mita, uye vanoshandisa LCD skrini kuratidza pH kuverenga. Aya mamita akanyanya uye akajeka kupfuura analog metres, asi anodhura zvakanyanya.
pH Meter Calibration
Calibration inhanho yakakosha mukuona kuti pH mita inopa kuverenga kwakaringana uye kwakaringana. Calibration inosanganisira kugadzirisa mita kuti ienderane nepH yemhinduro inozivikanwa. Kuti uenzanise pH mita, iwe unozoda seti yeyakajairwa mhinduro ine inozivikanwa pH kukosha. Iyi mhinduro dzinofanirwa kuvhara huwandu hwepH tsika dzauchange uchiyedza. Iyo pH mita inotanga kuverengerwa kune yakanyanya acidic kana basic standard solution, uyezve inoverengerwa kune yasara mhinduro kuitira kuwedzera pH.
Kugadziriswa kwepH Meter
Kuchengetedza kwakaringana kwema pH kwakakosha mukuona kuti inopa kuverenga kwakaringana uye kwakaringana. Mamwe matipi ekuchengetedza pH mita anosanganisira:
- Nguva dzose kuchenesa kweprobe uye electrodes
- Kuchengeta pH mita munzvimbo yakaoma uye inotonhorera
- Calibrating mita nguva dzose
- Kutsiva probe uye electrodes sezvinodiwa
