Uma sinethangi lezinhlanzi kubalulekile ukwazi izici nezidingo zezinhlobo esizinakekelayo. Okunye kokuguqukayo okubalulekile ukuze sikwazi ukuba nemvelo enhle ezindaweni zethu zasemanzini yi-pH. Amanzi anesilinganiso esithile se-asidi kuye ngamazinga okushisa nezici zawo. Ukuze wazi ukuthi yiliphi izinga le-pH elifanele kakhulu izinhlobo zethu, kukhona digital pH amamitha.
Kulesi sihloko sizochaza ukuthi ziyini amamitha we-digital pH bese senza ukukhetha okuhle kakhulu.
Yini i-digital pH metres
Ukwazi izici zamanzi noma indawo kubalulekile ukwazi amadigri angaba nawo maqondana ne-asidi noma i-alkalinity. Enye indlela yokukwenza kuphumelele, kusheshe futhi kunembile ukuthi ube namamitha we-digital pH. Kuyithuluzi elisebenziseka kakhulu futhi eliqonde kakhulu ukukwazi ukuthola amanani we-pH wamanzi noma wenhlabathi. Ngenxa yalokhu kunemba nesivinini ifile noma yaziwa ngokuhamba kwesikhathi.
Ngaphambi kokuthenga into enjengale kubalulekile ukwazi zonke izici eziyisisekelo kanye nohlobo lwayo, ukusetshenziswa nobukhulu bayo. Kunamamodeli amaningi ongakhetha kuwo nezinhlobonhlobo eziningi emakethe ongafuna umsebenzi onzima kakhulu. Ngakho-ke, ukubona kangcono amamodeli ahlukahlukene akhona futhi ukukusiza ukuthi yikuphi okufanela icala ngalinye, sizokwenza uhlobo lokuqhathanisa phakathi kwamamodeli aziwa kakhulu futhi asetshenziswe kakhulu.
Yini okufanele ibe khona ngamamitha we-digital pH
Ngeke wazi ukuthi iyiphi imitha engcono kakhulu uma ungazi ukuthi yimaphi amamitha we-digital pH okufanele abe nawo. Kuyadingeka ukwazi kahle ukuthi yiziphi izici zamakhemikhali zanoma yisiphi isixazululo noma uketshezi nokuningi uma sinezilwane ngaphakathi kwazo. Ngale divayisi ungazazi lezi zinto eziguqukayo kalula lapho usebenzisa futhi ufunda.
Izibalo ze-pH zizohlala zingamanani ukusuka ku-0 kuye ku-14 Futhi ngokuya ngemodeli oyikhethela ukusetshenziswa kwakho, ungabona izilinganiso kusikrini se-LCD. Sizohamba ngezingxenye sibona ukuthi le divayisi kumele ibe yini ukuze ibe sezingeni elifanele.
Into yokuqala okufanele uyazi ukusetshenziswa ukuthi uzonikeza idivayisi okukhulunywa ngayo. Ngokuya ngalokhu kusetshenziswa, singashintshanisa imodeli nohlobo lwedivayisi noma esizokhetha yona. Uma kungokokuqala usebenzisa lezi zinsimbi uzobona ukuthi ukusebenza kulula. Imane nje inomthwalo wokubala inani lezigidigidi ze-hydrogen ezisoketshezi noma emhlabathini lapho zisetshenziswa khona. Zonke izilinganiso ezingezansi kwamanani we-7 zizoba acidic futhi zonke izilinganiso ezingaphezulu kwe-8 zizoba yi-alkaline. Imvamisa uma amanani aphakathi kuka-7 no-8 kubhekwa njengevelu engathathi hlangothi.
Kunamamitha we-digital pH asebenza ngezintambo, kukhona nalawo anemichilo noma iphepha nephathekayo. Ama-laptops asebenza ngezindlela eziningi kakhulu futhi angasetshenziswa yibo bobabili ochwepheshe nabaqalayo. Banethuba lokuthi ungabayisa noma yikuphi njengoba bengenawo ama-plugs kepha kunalokho basebenze ngamabhethri. Ngaphezu kwalokho, zinezici eziyinkimbinkimbi futhi eziningi zazo ziletha umsebenzi wokunxeshezelwa kokushisa okuzenzakalelayo. Ngale ndlela, idivayisi uqobo lwayo ingaphatha kuphela ukubala ama-degree centigrade ento noma uketshezi esisebenza kulo futhi ngaleyo ndlela kukhulise ukunemba kokubala.
Zisetshenziswa kabanzi kwezolimo, izimboni, amachibi okubhukuda, phakathi kwezinye izindawo. Zijwayelekile impela ukuthi zisetshenziswe emanzini nasezikhungweni zenhlabathi ukwazi izakhiwo zamakhemikhali eziqukethe. Ingasetshenziswa futhi ekusetshenzisweni kwasekhaya okufana nesilinganiso ekulungisweni kwewayini elimnandi, ngoba amawayini ane-asidi ephansi kakhulu abhekwa njengomzimba omncane. Ibuye isetshenziselwe inqubo yokwenza ushizi.
Ibhethri, usayizi nokuklanywa
Lezi zinto eziguqukayo zibalulekile uma kukhulunywa ngokwazi ukuthi yiluphi uhlobo olulungele ukusetshenziswa kwakho. Njengoba uhlobo oluhle kakhulu olukhona yilolo olusebenza ngamabhethri, kufanele wazi ukuthi ayini amandla awo. Esinye sezici ezinomthelela empilweni yebhethri nesikhathi esingasetshenziswa ngaso uhlobo lwesakhiwo nesikrini se-LCD lapho idatha yesilinganiso izocaciswa ngokusobala.
Ngokusobala, uma isibuko sinokukhanyisa, ibhethri lingahlala kancane ngaphansi kwamanye amamodeli angenalo. Noma kunjalo, imodeli ngayinye inikeza isikhathi esithile sokuzimela.
Ngokuqondene nosayizi nokuklanywa, sekuvele kuncike kulokho ofuna ukukukhetha. Okusetshenziswa kakhulu futhi okusebenzisekayo ekusetshenzisweni kobungcweti yilawo angamakhompiyutha we-digital pH metres. Lokhu kuvumela ubukhulu babo ukuthi bube buphelele ukuze bakwazi ukubayisa cishe noma yikuphi. Kubalulekile ukuthi azigcini ngosayizi omncane kepha futhi zinesisindo esincane. Ngale ndlela, ngeke kudingeke usebenze kanzima kakhulu ukuze ukwazi ukuwasebenzisa noma ukuwahambisa.
Uma ubuza ukuthi malini amanani e-pH digital, sizoklelisa amanye amamodeli aziwa kakhulu futhi asetshenziswe kakhulu emakethe.
Amamitha we-digital pH amahle kakhulu
I-Preciva PH320001
Kungokunye okusebenzayo kakhulu okukhona. Ikhanya impela futhi ingathwalwa kalula lapho uyidinga khona. Enye yezinto ezimbi ezinkulu ukuthi ayilinganisi ngokuzenzakalela. Kunconywa ukuthi uyilinganise futhi njalo emavikini ama-4 ukuhlinzeka ngokusebenza kahle nokunemba kuzilinganiso. Ungayithenga ngokuchofoza lapha.
I-Gyo-yo SDWE234
Inobuchwepheshe besinxephezelo sokushisa okuzenzakalelayo obwenza bunembe kakhulu kunamanye amamodeli. Inomugqa wephutha ongu-0.05 kuphela. Inesikrini sohlobo lwe-LCD esinokukhanyisa ukuze ukubala ngakunye kubonakale kahle. Ezinye izimpushana ziyalahleka ukuze zikwazi ukulinganisa ithuluzi. Ungathenga lo mkhiqizo ngokuchofoza lapha.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngamamitha we-digital pH futhi ufunde ukuthi ungazuza kanjani ngalo.
