Uluvo lwe-PH
Isizukulwana esitsha se-PHTRSJ senzwa yomhlaba i-pH isombulula iintsilelo zomhlaba wendabuko pH efuna izixhobo zokubonisa ubuchwephesha, ukulinganisa okudinayo, ukuhlanganiswa okunzima, ukusetyenziswa kwamandla aphezulu, ixabiso eliphezulu, kwaye kunzima ukuthwala.
●Inzwa entsha ye-pH yomhlaba, ukuqonda ukubekwa esweni kwexesha lokwenyani kwi-intanethi ye-pH yomhlaba.
●Yamkela eyona dielectric eyomeleleyo yedielectric kunye nendawo enkulu yepolytetrafluoroethylene liquid junction, ekungekho lula ukuyivalela kunye nokugcinwa simahla.
●Ukuhlanganiswa okuphezulu, ubungakanani obuncinci, ukusetyenziswa kwamandla aphantsi, kulula ukuthwala.
●Ukuqonda ixabiso eliphantsi, ixabiso eliphantsi kunye nokusebenza okuphezulu.
●Ukuhlanganiswa okuphezulu, ubomi obude, ukulungeleka kunye nokuthembeka okuphezulu.
●Ukusebenza okulula.
●Xhasa uphuhliso lwesibini.
●I-electrode isebenzisa umgangatho ophezulu wentambo ephantsi yengxolo, enokwenza ubude besignali bufikelele kwiimitha ezingama-20 ngaphandle kokuphazamiseka.
Le mveliso ingasetyenziswa kakhulu kwimimandla yokunkcenkceshela kwezolimo, ukulima iintyatyambo, amadlelo engca, uvavanyo lomhlaba olukhawulezileyo, ukulinywa kwezityalo, imifuniselo yenzululwazi njalo njalo.

Ukubala ikhowudi ye-CRC:
1.Irejista ye-16-bit ecwangcisiweyo yi-FFFF kwi-hexadecimal (oko kukuthi, zonke ziyi-1).Tsalela le rejista kwirejista ye-CRC.
2.XOR idatha yokuqala ye-8-bit kunye ne-bit esezantsi ye-16-bit yerejista ye-CRC kwaye ubeke umphumo kwirejista ye-CRC.
3. Shifta imixholo yerejista ngasekunene ngesuntswana elinye (ukubhekisa kwisuntswana elisezantsi), gcwalisa eyona bit iphezulu ngo-0, kwaye ujonge eyona bit iphantsi.
4. Ukuba eyona bit ibalulekileyo ngu-0: phinda inyathelo lesi-3 (shift kwakhona), ukuba eyona bit ibalulekileyo ngu-1: irejista ye-CRC iXORed ngepolynomial A001 (1010 0000 0000 0001).
5. Phinda amanyathelo 3 kunye ne-4 kude kube ngamaxesha angama-8 ukuya ekunene, ukuze yonke idatha ye-8-bit iqhutywe.
6. Phinda amanyathelo 2 ukuya ku-5 kwi-8-bit elandelayo yokucubungula idatha.
7. Irejista ye-CRC ekugqibeleni ifunyenwe yikhowudi ye-CRC.
8. Xa isiphumo se-CRC sifakwe kwisakhelo solwazi, i-bits ephezulu kunye nephantsi iyatshintshwa, kwaye i-bit ephantsi iqala.
1.Xa i-sensor ishiya i-factory, i-probe inikezelwa ngekhava yokukhusela ecacileyo, kwaye i-liquid yokukhusela eyakhelwe-ngaphakathi ikhusela i-probe.Xa usebenzisa, nceda ususe isigqubuthelo sokukhusela, lungisa itanki yokucoca kunye nenzwa, kwaye usebenzise intambo yentambo eqhotyoshelweyo ukugubungela isihluzo kwitanki yokucoca.Ukuthintela ukudibana ngqo phakathi komhlaba kunye neprobe kunye nokonakalisa iprobe.Ekusetyenzisweni okuyinyani, nceda uqinisekise ukuba umkhombe wokucoca kunye necebo lokucoca ziqhagamshelwe ngokuqinileyo.Musa ukususa umkhombe wokucoca kunye nesihluzo.Faka i-probe ngqo emhlabeni ukunqanda ukwenza umonakalo weprobe kwaye ungalungiseki.
2. Faka inxalenye yeprobe ngokuthe nkqo emhlabeni.Ubunzulu beprobe kufuneka bugqunywe sisihluzo.Kwiimeko eziqhelekileyo, i-pH emoyeni iphakathi kwe-6.2 kunye ne-7.8.
3.Emva kokungcwaba inzwa, uthele umlinganiselo othile wamanzi malunga nomhlaba ukuba ulinganiswe, ulinde imizuzu embalwa, kwaye ulinde ukuba amanzi adibanise kwi-probe, ngoko unokufunda idatha kwisixhobo.Phantsi kweemeko eziqhelekileyo, umhlaba awuthathi hlangothi kwaye i-pH iphakathi kwe-Around 7, ixabiso lokwenyani le-pH yomhlaba kwiindawo ezahlukeneyo liya kwahluka, kufuneka limiselwe ngokwemeko yokwenyani.
4.Umsebenzisi unokusebenzisa ii-reagents ze-pH ezi-3 eziqhotyoshelweyo kwaye uqwalasele ngokwendlela yokuqwalasela ukujonga ukuba ukusebenza kwemveliso kuqhelekileyo.
1. Kwimibhobho ukuze kuqinisekiswe ukuba i-electrode echanekileyo elinganiswe ixabiso le-pH kufuneka igwenywe ngexesha lokulinganisa amaqamza omoya okubangelwa idatha engachanekanga;
2. Nceda ujonge ukuba ukupakishwa kusemgangathweni kwaye ujonge ukuba imodeli yemveliso iyahambelana nokukhetha;
3. Musa ukudibanisa ngombane, kwaye emva koko uvule emva kokujonga i-wiring.
4. Musa ukutshintsha izinto okanye iingcingo ezithe zathengiswa xa imveliso iphuma kumzi-mveliso.
5. Uluvo sisixhobo esichanekileyo.Nceda ungayiqhawuli ngokwakho okanye uchukumise umphezulu wenzwa ngezinto ezibukhali okanye ulwelo oludlekayo ngexesha lokusetyenziswa ukunqanda ukonakalisa imveliso.
6.Nceda ugcine isatifikethi sokuqinisekisa kunye nesatifikethi sokuhambelana, kwaye usibuyisele kunye nemveliso xa ulungisa.
1.Kwimveliso ye-analog, umboniso ubonisa ukuba ixabiso ngu-0 okanye liphumile kuluhlu.Umqokeleli akanakukwazi ukufumana ulwazi ngokuchanekileyo ngenxa yeengxaki zocingo.Nceda ujonge ukuba i-wiring ichanekile kwaye yomelele, kwaye amandla ombane aqhelekileyo;
2.Ukuba ayizizo zizathu zingasentla, nceda uqhagamshelane nomvelisi.
1.Ukuphela kwegalelo lesixhobo (i-socket electrode yokulinganisa) kufuneka igcinwe yomile kwaye icocekile ukukhusela uthuli kunye nomphunga wamanzi ukuba ungangeni.
2. Gwema ukucwiliswa kwexesha elide le-electrodes kwisisombululo seprotheni kunye nesisombululo se-asidi fluoride, kwaye ugweme ukudibanisa neoli ye-silicone.
3.Emva kokusetyenziswa kwexesha elide le-electrode, ukuba ithambeka lincitshiswe kancinane, isiphelo esisezantsi se-electrode sinokuntywiliselwa kwisisombululo se-4% se-HF (i-hydrofluoric acid) imizuzwana emi-3 ukuya kwemi-5, emva koko ihlanjwe ngamanzi ane-distilled emva koko ifakwe emanzini. I-0.1mol / L i-hydrochloric acid Hlaziya i-electrode.
4.Ukuze wenze umlinganiselo uchaneke ngakumbi, i-electrode kufuneka ihlanjwe rhoqo kwaye ihlanjwe ngamanzi adibeneyo.
5. Isidluliseli kufuneka sibekwe kwindawo eyomileyo okanye kwibhokisi yokulawula ukunqanda ukuvuza kwemitha okanye impazamo yokulinganisa ebangelwa ngamathontsi amanzi atshizayo okanye ukuba manzi.
