Umkhiqizi we-Biobase 2 Points Pocket Calibration Pocket Isihloli se-pH

Sihlale sicabanga futhi sizijwayeza okuhambisana nokushintsha kwesimo, futhi sikhule.Sihlose ukuzuza ingqondo nomzimba ocebile kanye nokuphilela Umkhiqizi we-Biobase 2 Points Push-Button Calibration Pocket pH Tester, Siyakwamukela ukuthi uye kithi noma nini ukuze kusungulwe uxhumano lwebhizinisi.
Sihlale sicabanga futhi sizijwayeza okuhambisana nokushintsha kwesimo, futhi sikhule.Sihlose ukuzuza ingqondo nomzimba ocebile kanye nokuphilaI-China pH Tester Digital Meter kanye ne-pH Tester Drop, Uma usinika uhlu lwezixazululo onentshisekelo kuzo, kanye namamodeli namamodeli, singakuthumela amakhotheshini.Qiniseka ukuthi usithumele i-imeyili ngokuqondile.Umgomo wethu uwukusungula ubudlelwano bebhizinisi besikhathi eside nobunenzuzo ngokuhlanganyela namakhasimende asekhaya nawaphesheya kwezilwandle.Sibheke ngabomvu ukuthola impendulo yakho maduze.

Inzwa ye-pH yenhlabathi yesizukulwane esisha ye-PHTRSJ ixazulula ukushiyeka kwe-pH yenhlabathi yendabuko edinga amathuluzi wokubonisa ochwepheshe, ukulinganisa okuyisicefe, ukuhlanganiswa okunzima, ukusetshenziswa kwamandla okuphezulu, intengo ephezulu, kanye nobunzima bokuthwala.

● Inzwa entsha ye-pH yenhlabathi, eqaphela ukuqapha kwesikhathi sangempela ku-inthanethi kwe-pH yenhlabathi.
● Isebenzisa i-dielectric eqinile ethuthuke kakhulu nendawo enkulu ye-polytetrafluoroethylene liquid junction, okungelula ukuyivimba futhi ingalungiseki.
● Ukuhlanganiswa okuphezulu, usayizi omncane, ukusetshenziswa kwamandla okuphansi, ukuthwala kalula.
● Bona izindleko eziphansi, intengo ephansi nokusebenza okuphezulu.
● Ukuhlanganiswa okuphezulu, impilo ende, ukunethezeka nokuthembeka okuphezulu.
● Ukusebenza okulula.
● Sekela ukuthuthukiswa kwesibili.
● I-electrode isebenzisa ikhebula yekhwalithi ephezulu yomsindo ophansi, engenza ubude bokukhipha isignali bufike kumamitha angu-20 ngaphandle kokuphazamiseka.

Lo mkhiqizo ungasetshenziswa kakhulu emikhakheni yokuchelela ngenkasa yezolimo, ingadi yezimbali, amadlelo emathafeni, ukuhlola umhlabathi ngokushesha, ukutshalwa kwezitshalo, ukuhlolwa kwesayensi nokunye.

Uhlobo lwe-voltage (0 ～ 5V okukhiphayo):
D = V / 5 × 14
(D inani le-pH elilinganisiwe, 0.00pH≤D≤14.00pH, V i-voltage ephumayo (V))

Uhlobo lwamanje (4 ～ 20mA okukhiphayo):
D = (I-4) / 16 × 14
(D inani le-pH elilinganiselwe, 0.00pH≤D≤14.00pH, mina ngingumphumela wamanje (mA))

(1) Uma ifakwe isiteshi sezulu esikhiqizwe yinkampani yethu, xhuma ngqo inzwa kusixhumi esibonakalayo esihambelanayo esiteshini sezulu usebenzisa ulayini wezinzwa.
(2) Uma i-transmitter ithengwa ngokwehlukana, ukulandelana kwekhebula komthumeli kuthi:

1.Ifomethi ye-serial
I-data bits 8 bits
Misa kancane 1 noma 2
Hlola Idijithi Ayikho
Isilinganiso se-Baud 9600 Isikhawu sokuxhumana okungenani singu-1000ms
2.Ifomethi yokuxhumana
[1] Bhala ikheli ledivayisi
Thumela: 00 10 Ikheli CRC (5 bytes)
Izimbuyiselo: 00 10 CRC (4 bytes)
Qaphela: 1. Ingxenye yekheli lomyalo wekheli lokufunda nokubhala kufanele libe ngu-00.
2. Ikheli liyibhayithi elingu-1 futhi ububanzi bungu-0-255.
Isibonelo: Thumela 00 10 01 BD C0
Ibuyisela 00 10 00 7C
[2] Funda ikheli ledivayisi
Thumela: 00 20 CRC (4 bytes)
Izimbuyiselo: 00 20 Adress CRC (5 bytes)
Incazelo: Ikheli ngu-1 byte, ububanzi bungu-0-255
Isibonelo: Thumela u-00 20 00 68
Ibuyisela 00 20 01 A9 C0
[3] Funda idatha yesikhathi sangempela
Thumela: Ikheli 03 00 00 00 01 XX XX
Qaphela: njengoba kukhonjisiwe ngezansi:

Ukubuyisela: Ikheli 03 02 XX XX XX XX

Ukuze ubale ikhodi ye-CRC:
1.Irejista ye-16-bit esethiwe ngaphambilini ithi FFFF nge-hexadecimal (okungukuthi, zonke zingu-1).Shayela le rejista ngerejista ye-CRC.
2.XOR idatha yokuqala ye-8-bit enebhithi engezansi yerejista ye-CRC engu-16 futhi ifake umphumela kurejista ye-CRC.
3.Shifta okuqukethwe kwerejista kwesokudla ngebhithi eyodwa (ubheke kwencane), gcwalisa ibhithi ephezulu kakhulu ngo-0, bese uhlola ephansi kakhulu.
4.Uma ibhithi ebaluleke kakhulu ingu-0: phinda isinyathelo sesi-3 (shintsha futhi), uma okuncane okubalulekile kungu-1: irejista ye-CRC ifakwe ku-XORed nge-polynomial A001 (1010 0000 0000 0001).
5.Phinda izinyathelo 3 no-4 kuze kube izikhathi ezingu-8 kwesokudla, ukuze yonke idatha ye-8-bit icutshungulwe.
6.Phinda izinyathelo 2 kuya kwezi-5 ukuze uthole ukucubungula kwedatha okungu-8-bit.
7.Irejista ye-CRC ekugcineni itholakele ikhodi ye-CRC.
8.Uma umphumela we-CRC ufakwa ohlakeni lolwazi, amabhithi aphezulu naphansi ayashintshaniswa, bese kuthi kancane kuqala.

1.Lapho inzwa iphuma efektri, i-probe inikezwa isembozo sokuvikela esisobala, futhi uketshezi olwakhelwe ngaphakathi oluvikelayo luvikela uphenyo.Uma usebenzisa, sicela ususe ikhava eyisivikelo, ulungise ithange lokuhlunga kanye nenzwa, bese usebenzisa intambo yekhebula enamathiselwe ukugoqa isihlungi ethangini lesihlungi.Ukuvimbela ukuthintana okuqondile phakathi kwenhlabathi kanye ne-probe futhi kulimaze i-probe.Ekusetshenzisweni kwangempela, sicela uqinisekise ukuthi i-trough yokuhlunga nesihlungi kuxhumeke ngokuqinile.Ungawususi umkhombe wokuhlunga kanye nesihlungi.Faka i-probe ngqo emhlabathini ukugwema ukwenza umonakalo we-probe futhi ungalungiseki.
2.Faka ingxenye ye-probe iqonde emhlabathini.Ukujula kwe-probe kumele okungenani kuhlanganiswe isihlungi.Ngaphansi kwezimo ezijwayelekile, i-pH esemoyeni iphakathi kuka-6.2 no-7.8.
3.Ngemuva kokungcwaba inzwa, uthele inani elithile lamanzi emhlabeni ukuze ulinganiswe, ulinde imizuzu embalwa, bese ulinda ukuthi amanzi angene ku-probe, khona-ke ungafunda idatha kuthuluzi.Ngaphansi kwezimo ezijwayelekile, inhlabathi ayithathi hlangothi futhi i-pH iphakathi kwe-Around 7, inani langempela le-pH lenhlabathi ezindaweni ezahlukene lizohluka, kufanele kunqunywe ngokuvumelana nesimo sangempela.
4.Umsebenzisi angasebenzisa ama-reagents e-pH angu-3 anamathiselwe futhi alungiselele ngokwendlela yokumisa ukuze ahlole ukuthi ukusebenza komkhiqizo kujwayelekile yini.

1.Epayipini ukuze kuqinisekiswe ukuthi i-electrode elinganisiwe ivelu ye-pH kufanele igwenywe ngesikhathi sokukalwa kwamabhamuza omoya abangelwa idatha engalungile;
2.Sicela uhlole ukuthi ingabe iphakheji iphelele futhi uhlole ukuthi imodeli yomkhiqizo iyahambisana yini nokukhetha;
3.Ungaxhumi uma ukhanyisa, bese uvula ngemuva kokuhlola izintambo.
4.Ungashintshi ngokuzenzakalelayo izingxenye noma izintambo ezidayisiwe lapho umkhiqizo uphuma efekthri.
5.Inzwa iyidivayisi enembayo.Sicela ungayiqaqi uwedwa noma uthinte ingaphezulu lenzwa ngezinto ezicijile noma uketshezi olubolayo phakathi nokusetshenziswa ukuze ugweme ukulimaza umkhiqizo.
6.Sicela ugcine isitifiketi sokuqinisekisa nesitifiketi sokuvumelana, futhi usibuyisele kanye nomkhiqizo lapho ulungisa.

1.Ukuze uthole okukhiphayo kwe-analog, isibonisi sibonisa ukuthi inani lingu-0 noma lingaphandle kobubanzi.Umqoqi angase angakwazi ukuthola ulwazi ngendlela efanele ngenxa yezinkinga zezintambo.Sicela uhlole ukuthi izintambo zilungile futhi ziqinile, futhi i-voltage yamandla ijwayelekile;
2.Uma kungezona izizathu ezingenhla, sicela uxhumane nomkhiqizi.

1.Isiphetho sokufakwayo kwethuluzi (isokhethi ye-electrode yokulinganisa) kufanele igcinwe yomile futhi ihlanzekile ukuze kuvinjelwe ukungena kothuli nomhwamuko wamanzi.
2.Gwema ukucwiliswa isikhathi eside kwama-electrode esixazululweni seprotheni nesisombululo se-acid fluoride, futhi ugweme ukuthintana nowoyela we-silicone.
3.Ngemuva kokusetshenziswa isikhathi eside kwe-electrode, uma umthambeka wehliswa kancane, indawo engezansi ye-electrode ingacwiliswa kusixazululo esingu-4% se-HF (hydrofluoric acid) imizuzwana emi-3 kuya kwemi-5, bese igezwa ngamanzi acwecwe bese icwiliswa. 0.1mol / L i-hydrochloric acid Vuselela i-electrode.
4.Ukuze wenze ukulinganisa kunembile, i-electrode kufanele ilinganiswe kaningi futhi igezwe ngamanzi acwecwe.
5.I-transmitter kufanele ibekwe endaweni eyomile noma ibhokisi lokulawula ukugwema ukuvuza kwamamitha noma iphutha lokulinganisa elibangelwa amaconsi amanzi afafaza noma abe manzi.

Sihlale sicabanga futhi sizijwayeza okuhambisana nokushintsha kwesimo, futhi sikhule.Sihlose ukuzuza ingqondo nomzimba ocebile kanye nokuphilela Umkhiqizi we-Biobase 2 Points Push-Button Calibration Pocket pH Tester, Siyakwamukela ukuthi uye kithi noma nini ukuze kusungulwe uxhumano lwebhizinisi.
Umkhiqizi weI-China pH Tester Digital Meter kanye ne-pH Tester Drop, Uma usinika uhlu lwezixazululo onentshisekelo kuzo, kanye namamodeli namamodeli, singakuthumela amakhotheshini.Qiniseka ukuthi usithumele i-imeyili ngokuqondile.Umgomo wethu uwukusungula ubudlelwano bebhizinisi besikhathi eside nobunenzuzo ngokuhlanganyela namakhasimende asekhaya nawaphesheya kwezilwandle.Sibheke ngabomvu ukuthola impendulo yakho maduze.
