pH mitandiconductivity mitaamagwiritsidwa ntchito kwambiri zida zowunikira pakufufuza kwasayansi, kuyang'anira chilengedwe, ndi njira zopangira mafakitale. Ntchito yawo yolondola komanso kutsimikizira kwa metrological kumadalira kwambiri mayankho omwe amagwiritsidwa ntchito. Phindu la pH ndi mphamvu zamagetsi zazitsulozi zimakhudzidwa kwambiri ndi kusiyana kwa kutentha. Pamene kutentha kumasintha, magawo onsewa amasonyeza mayankho osiyana, omwe angakhudze kulondola kwa kuyeza. Pakutsimikizira kwa metrological, zawoneka kuti kugwiritsa ntchito molakwika zowongolera kutentha pazida izi kumabweretsa kupatuka kwakukulu pazotsatira zoyezera. Komanso, ogwiritsa ntchito ena samamvetsetsa mfundo zazikuluzikulu za kubwezera kutentha kapena kulephera kuzindikira kusiyana pakati pa pH ndi ma conductivity mamita, zomwe zimapangitsa kugwiritsa ntchito molakwika ndi deta yosadalirika. Choncho, kumvetsetsa bwino mfundo ndi kusiyanitsa pakati pa njira zolipirira kutentha kwa zida ziwirizi ndizofunikira kuti zitsimikizire kulondola kwa kuyeza.

I. Mfundo ndi Ntchito za Olipiritsa Kutentha

1. Kutentha Kulipiridwa mu pH Mamita
Poyesa ndikugwiritsa ntchito ma pH metres, miyeso yolakwika nthawi zambiri imabwera chifukwa chogwiritsa ntchito molakwika chowongolera kutentha. Ntchito yayikulu ya chowongolera kutentha kwa mita ya pH ndikusintha momwe ma elekitirodi amayankhira molingana ndi Nernst equation, zomwe zimathandiza kudziwa molondola pH ya yankho pa kutentha komwe kulipo.

Kusiyana komwe kungatheke (mu mV) kopangidwa ndi njira yoyezera ma elekitirodi kumakhalabe kosasintha mosasamala kanthu za kutentha; komabe, kukhudzika kwa kuyankha kwa pH-ie, kusintha kwa magetsi pa unit pH-kusiyana ndi kutentha. Nernst equation imatanthawuza ubalewu, kuwonetsa kuti kutsetsereka kwa ma electrode kumawonjezeka ndi kutentha kokwera. Pamene compensator kutentha kutsegulidwa, chidacho chimasintha chinthu chosinthika molingana, kuonetsetsa kuti mtengo wa pH womwe ukuwonetsedwa ukugwirizana ndi kutentha kwenikweni kwa yankho. Popanda kubwezera koyenera kwa kutentha, pH yoyezedwa ingawonetse kutentha kofanana osati kutentha kwachitsanzo, zomwe zimayambitsa zolakwika. Chifukwa chake, kubweza kutentha kumalola kuyeza kodalirika kwa pH m'malo osiyanasiyana otentha.

2. Malipiro a Kutentha mu Conductivity Meters
Magetsi madutsidwe zimadalira mlingo wa ionization wa electrolytes ndi kuyenda kwa ayoni mu njira, onse amene amadalira kutentha. Pamene kutentha kumawonjezeka, kuyenda kwa ionic kumawonjezeka, zomwe zimapangitsa kuti pakhale ma conductivity apamwamba; mosiyana, kutentha m'munsi kumachepetsa madutsidwe. Chifukwa cha kudalira kwakukulu uku, kufananitsa mwachindunji miyeso ya conductivity yomwe imatengedwa pa kutentha kosiyana sikuli kofunikira popanda kukhazikika.

Kuti muwonetsetse kufananitsa, kuwerengera kwa ma conductivity nthawi zambiri kumatanthawuza kutentha kokhazikika - nthawi zambiri 25 ° C. Ngati compensator kutentha ndi wolumala, chida lipoti madutsidwe pa kutentha kwenikweni yankho. Zikatero, kuwongolera pamanja pogwiritsa ntchito kutentha koyenera (β) kuyenera kugwiritsidwa ntchito kuti kusinthaku kukhale kutentha komwe kumatchulidwa. Komabe, pamene compensator ya kutentha yayatsidwa, chidacho chimapanga kusintha kumeneku kutengera chiwerengero cha kutentha chomwe chimakonzedweratu kapena chosinthika. Izi zimathandizira kufananitsa kosasinthika pamasampulo onse ndikuthandizira kutsata miyezo yoyang'anira makampani. Potengera kufunika kwake, ma conductivity mita amakono pafupifupi padziko lonse lapansi amaphatikiza magwiridwe antchito a chipukuta misozi, ndipo njira zotsimikizira za metrological ziyenera kuphatikizapo kuwunika kwa gawoli.

II. Malingaliro Ogwira Ntchito a pH ndi Ma Conductivity Meters okhala ndi Malipiro a Kutentha

1. Malangizo Ogwiritsira Ntchito pH Meter Temperature Compensators
Popeza kuti chizindikiro cha mV choyezedwa sichisiyana ndi kutentha, ntchito ya compensator kutentha ndikusintha otsetsereka (conversion coefficient K) ya yankho la electrode kuti lifanane ndi kutentha komwe kulipo. Chifukwa chake, ndikofunikira kuwonetsetsa kuti kutentha kwazitsulo zomwe zimagwiritsidwa ntchito pakuwongolera zikugwirizana ndi zomwe zikuyezedwa, kapena kuti chipukuta misozi cholondola chikugwiritsidwa ntchito. Kulephera kutero kungayambitse zolakwika mwadongosolo, makamaka poyesa zitsanzo kutali ndi kutentha kwa calibration.

2. Malangizo Ogwiritsira Ntchito Conductivity Meter Temperature Compensators
Choyezera chowongolera kutentha (β) chimagwira ntchito yofunika kwambiri pakusintha kusinthasintha koyezera kukhala kutentha komwe kumatchulidwa. Mayankho osiyanasiyana amawonetsa ma β mosiyanasiyana-mwachitsanzo, madzi achilengedwe amakhala ndi β pafupifupi 2.0-2.5 %/°C, pomwe ma asidi amphamvu kapena maziko amatha kusiyana kwambiri. Zida zokhala ndi zowongolera zokhazikika (monga 2.0 %/°C) zitha kuyambitsa zolakwika poyesa njira zomwe sizili mulingo. Pazogwiritsidwa ntchito bwino kwambiri, ngati coefficient yomangidwayo silingasinthidwe kuti ifanane ndi β yeniyeni ya yankho, tikulimbikitsidwa kuletsa ntchito yolipirira kutentha. M'malo mwake, yesani kutentha kwa yankho molondola ndikuwongolera pamanja, kapena sungani chitsanzocho pa 25 ° C panthawi yoyezera kuti muchotse kufunikira kwa chipukuta misozi.

III. Njira Zowunikira Mwachangu Zodziwira Zosokonekera mu Ma Compensators Kutentha

1. Njira Yoyang'ana Mwamsanga ya pH Meter Temperature Compensators
Choyamba, yang'anani mita ya pH pogwiritsa ntchito njira ziwiri zokhazikika kuti mukhazikitse malo otsetsereka. Kenako, yesani njira yachitatu yotsimikizika yotsimikizika pansi pamikhalidwe yolipiridwa (ndi chipukuta misozi cha kutentha). Yerekezerani zowerengera zomwe mwapeza ndi mtengo wa pH womwe ukuyembekezeredwa pa kutentha kwenikweni kwa yankho, monga momwe zafotokozedwera mu "Verification Regulation for pH Meters." Ngati kupatuka kupitilira cholakwika chachikulu chovomerezeka cha kalasi yolondola ya chida, chowongolera kutentha chikhoza kukhala chosagwira ntchito ndipo chimafuna kuwunika akatswiri.

2. Quick Chongani Njira ya Conductivity Meter Kutentha Compensators
Yesani madulidwe ndi kutentha kwa njira yokhazikika pogwiritsa ntchito mita ya conductivity ndi chipukuta misozi cha kutentha. Lembani mtengo wamtengo wapatali womwe wawonetsedwa. Kenako, zimitsani kutentha compensator ndi kulemba madutsidwe yaiwisi pa kutentha kwenikweni. Pogwiritsa ntchito choyezera cha kutentha chodziwika cha yankho, werengerani momwe mungayendetsere pa kutentha (25 ° C). Yerekezerani mtengo wowerengeredwa ndi zomwe zidalipidwa zomwe zidawerengedwa. Kusiyana kwakukulu kumawonetsa vuto lomwe lingakhalepo pakusintha kwa kutentha kwa ma aligorivimu kapena sensa, zomwe zikufunika kutsimikiziranso ndi labotale yotsimikizika ya metrology.

Pomaliza, ntchito zolipirira kutentha mu pH metres ndi ma conductivity metres zimagwira ntchito zosiyanasiyana. Mu ma pH metres, chipukuta misozi chimasintha kayankhidwe ka electrode kuti iwonetse kutentha kwanthawi yeniyeni malinga ndi Nernst equation. Mu ma conductivity metres, chipukuta misozi chimapangitsa kuwerengera kwa kutentha kuti athe kufananitsa zitsanzo. Kusokoneza njirazi kungayambitse kutanthauzira kolakwika ndi kusokoneza khalidwe la deta. Kumvetsetsa bwino mfundo zawo kumatsimikizira miyeso yolondola komanso yodalirika. Kuphatikiza apo, njira zowunikira zomwe zafotokozedwa pamwambapa zimalola ogwiritsa ntchito kuyesa koyambirira kwa momwe amachitira compensator. Zikadziwika kuti pali zolakwika, kuperekedwa mwachangu kwa chida chotsimikizira za metrological ndikofunikira.
