Chii chinonzi Pocket PH Testers?
Zviyedzo zvepocket pH zvishandiso zvidiki zvinotakurika zvinopa ruzivo kumushandisi nemazvo, zviri nyore uye zvinokwanisika kutenga. Zvishandiso izvi zvakagadzirirwa kushandiswa mumamiriro akasiyana uye zvinoedza alkalinity (pH) uye acidity yesampuli dzakasiyana-siyana. Zvinonyanya kufarirwa pakuedza sampuli dzemhando yepamusoro yemvura nekuti dzinokwana zvakanaka muhomwe kuti zvive nyore kutora nekushandisa.
Nekushandisa kwakasiyana-siyana kunogadzira mhando dzakasiyana dzesamples, zvakakosha kuziva kuti rudzii rwe pH water tester ruchaburitsa mhedzisiro yakanakisa kune zvaunoda pakuyedza sample. Kune mhando dzakasiyana dzetesters dziri pamusika dzinopa mhando dzakasiyana dzetekinoroji kuti dzigutse zvinodiwa nemutengi. Kune mhando nhatu dze pH water testers dzakanakira kuyedza mhando yemvura: single-junction electrode disposable tester, single-junction replaceable electrode uye double-junction replaceable electrode. Kusarudza pH meter yemvura kunoenderana zvakanyanya nesample iri kuyedzwa, cadence yekuyedza uye kururama kunodiwa.
pH Kukosha
Mhando yebvunzo yemhando yemvura inonyanya kuzivikanwa ndeyebvunzo yepH. pH yemvura inoratidza kuenzana pakati pehydrogen ions, dziri acidic, uye hydroxide ions, dziri nyore. Kuenzana kwakakwana kwezvose zviri zviviri kuri pa pH ye7. pH ye7 haina neutral. Sezvo nhamba yacho ichidzikira, chinhu ichi chinoonekwa seacidic yakawanda; sezvachinowedzera, chinowedzera alkaline. Makoshero acho anotangira pa 0 (total acid, senge battery acid) kusvika pa 14 (full alkaline, semuenzaniso, drain cleaner). Mvura yepombi inowanzova pa pH ye7, nepo mvura dzinowanikwa muchimiro chega dzinowanzova pakati pe6 kusvika ku8 pH units. Mashandisirwo anoda kuyera pH anowanikwa muindasitiri yega yega nedzimba. Mashandisirwo epamba, akadai sekuyera pH ye aquarium yehove, akasiyana nekuyera pH yemvura mu plant yekuchenesa mvura.
Usati wasarudza pocket tester, zvakakosha kuziva zvakawanda nezve electrode. Ndiyo chikamu chepocket tester chinonyikwa musampuli kuti chiyereswe pH. Mukati me electrode mune electrolyte (mvura kana gel). Electrode junction ndiyo porous point iri pakati pe electrolyte iri mu electrode nesampuli yako. Chaizvoizvo, electrolyte inofanira kubuda musampuli kuitira kuti electrode ishande kuti iwane mhedzisiro chaiyo. Zvikamu zvidiki zvese izvi zvinoshanda pamwe chete mukati me electrode kuti zviyere pH nemazvo.
Electrode inoora zvishoma nezvishoma nekuti electrolyte inogara ichishandiswa pakutora zviyero uye inocheneswa nemaion kana macompounds anosvibisa. Maion anochetura electrolyte isimbi, phosphates, sulfates, nitrates nemapuroteni. Kana nharaunda ine caustic yakawanda, kukanganisa kwakanyanya paelectrode. Nzvimbo dzine caustic dzine huwandu hwakawanda hwemaion anosvibisa, senge nzvimbo dzekurapa mvura yakasviba, dzinogona kukurumidzisa chepfu ye electrolyte. Maitiro aya anogona kuitika nekukurumidza nevayedzi vekutanga vakachipa. Mukati memavhiki, mamita anogona kunonoka uye kusachinja-chinja. Pocket pH meter yemhando yepamusoro ichave neelectrode yakavimbika inopa kuverenga kwakasimba uye kwakarurama nguva dzose. Kuchengeta electrode yakachena uye yakanyorova kwakakoshawo pakushanda kwepocket tester uye kurarama kwenguva refu.
Vaongorori vepH vanoraswa muchikamu chimwe chete
Kune vanoshandisa vanoedza pH nguva nenguva vane pH yemuenzaniso wemvura wakafanana, tekinoroji iri nyore inoshandisa electrode ine mubatanidzwa mumwe chete inopa simba rakawanda uye kururama. Electrode ine mubatanidzwa mumwe chete inogara kwenguva pfupi pane electrode ine mubatanidzwa mumwe chete uye inowanzo shandiswa pakuedza pH nekupisa nguva nenguva. Sensor ine mubatanidzwa mumwe chete isingatsiviwe ine pH ye +0.1. Iyi isarudzo inodhura zvishoma uye inowanzo tengwa nemushandisi asina hunyanzvi. Kana muongorori asingachape kuverenga kwakarurama, ingoirasa wotenga imwe pocket tester. Vanoedza vanodyara vane mubatanidzwa mumwe chete vanowanzo shandiswa mu hydroponics, aquaculture, potable water, aquariums, pool and spas, education, uye bindu markets.
Vaongorori vepH veElectrode inotsiviwa neMumwe Chete
Danho rakakwirira kubva pa single-junction disposable tester ndiyo single-junction replaceable pocket tester, iyo inogona kuwana kururama kuri nani kwe +0.01 pH. Iyi tester yakakodzera maitiro mazhinji eASTM Intl. uye US EPA test. Sensor inogona kutsiviwa, ichichengetedza unit, saka inogona kushandiswa kakawanda. Kutsiva sensor isarudzo yemushandisi asingawanzo shandisa tester nguva dzose. Kana unit ichishandiswa nguva dzose uye samples dziine huwandu hwakawanda hwemaion anokuvadza electrolyte mu electrode, zvingave zvakanaka kutamira kune imwe nhanho yevayedzi vachishandisa tekinoroji ye double-junction electrodes.
Vaongorori vepH veElectrode vanotsiviwa neDouble-Junction
Tekinoroji yekubatanidza kaviri inopa nzira refu yekufamba kwezvinhu zvinosvibisa, ichinonotsa kukuvara kunoparadza electrode yepH, ichivandudza uye ichiwedzera hupenyu hweyuniti. Kusvibiswa kusati kwasvika kuelectrode, kunofanirwa kupararira kwete kuburikidza nejunction imwe chete, asi kuburikidza nejunction mbiri. Vayedzi vekubatanidza kaviri vayedzi vane basa guru, vane hunhu hwepamusoro vanokwanisa kutsungirira mamiriro akaomarara uye masampuli. Vanogona kushandiswa nemvura yakasviba, mhinduro dzine sulfides, simbi dzinorema uye Tris buffers. Kune vatengi vanoda kuramba vachidzokorora bvunzo dzavo dzepH, vachiisa masensa kuzvinhu zvine simba, zvakakosha kushandisa double-junction tester kuti vawedzere hupenyu hweelectrode uye kuve nechokwadi chekuti yakarurama, zvakare. Nekushandisa kwega kwega, kuverenga kuchadonha uye kusavimbika. Dhizaini yekubatanidza kaviri inoita kuti hunhu hwepamusoro uye tekinoroji inoshandiswa kuyera mazinga epH pakururama kwakanyanya kwe +0.01 pH.
Kugadzirisa pH kwakakosha kuti pave nekururama. Hazviwanzoitika kuti pH meter ibve panzvimbo dzayo dzakagadziriswa. Kana yangodaro, mhinduro dzisina kururama dzinogona kuitika. Zvakakosha kugadzirisa vanoedza kuti vawane zviyero zvakarurama. Mamwe ma pH pocket metres ane automatic buffer recognition, zvichiita kuti kugadzirisa kuve nyore uye nekukurumidza. Mazhinji emamodheru asingadhuri anoda kugadziriswa kakawanda kuti ave nechokwadi chekuti zviyero zvakarurama. Kugadzirisa pH kunofanirwa kuitwa nguva dzose, zvichikurudzirwa zuva nezuva kana kanenge kamwe chete pasvondo. Gadzirisa kusvika pamapoinzi matatu uchishandisa US kana National Institute of Standards and Technology buffer set standards.
Vayedzi vepocket testers vanga vachinyanya kushandisa nzira dzekuongorora mvura mumakore apfuura, sezvo dziri diki, dzinotakurika, dzakarurama uye dzinogona kuburitsa kuverenga mumasekondi mashoma nekudzvanya bhatani. Sezvo musika wevayedzi uchiramba uchida shanduko, vagadziri vakawedzera zvinhu zvakaita sedzimba dzisingapindi mvura uye dzisingapindi guruva kudzivirira vayedzi kubva kunzvimbo dzakanyorova uye kusabatwa zvakanaka. Pamusoro pezvo, zviratidziro zvikuru, zvinogadzirisa maitiro ekuverenga zvinoita kuti kuverenga kuve nyore. Kubhadharisa tembiricha otomatiki, chinhu chinowanzo chengeterwa mamaira ekubata nemaoko uye ebhenji, chakawedzerwawo kumamodheru matsva. Mamwe mamodheru anokwanisa kuyera nekuratidza tembiricha chaiyo. Vayedzi vepamusoro vane kugadzikana, calibration uye zviratidzo zvebhatiri pachiratidziro uye vanodzima otomatiki kuchengetedza hupenyu hwebhatiri. Kusarudza muyedzi wepocket wakakodzera wechishandiso chako kuchakupa kushandiswa kwakavimbika uye kwakarurama nguva dzose.
