SUP-PH5019 Plastic pH Sensor Probe, pH Sensor Electrode, Metsi pH Sensor bakeng sa Indasteri le Laboratori
Selelekela
Ena ea moruometsi pH electrodee kopanya lesela le thata la khalase, li-electrolyte tsa gel, le sistimi ea litšupiso tse kopanyang habeli ka har'a 'mele oa polasetiki o matsutla, e felisa likarolo tse senyehang tsa khalase tse pepesehileng tšenyo ea mochini. Diaphragm ya sebaka se seholo sa PTFE e fokotsa ho hoholeha ho ka bang teng mme e hanela ho thiba ho tswa ho metswako kapa pula.
Ka linako tse arabelang ka potlako (<1 motsotso o tloaelehileng), botsitso bo babatsehang khahlanong le li-acids tse matla / alkalis, le ho lumellana le li-transmitters tse ngata tsa pH ka BNC kapa ka ho toba cable output, SUP-PH5019 digital pH sensor e fana ka tlhokomelo e nepahetseng, e tlaase ea tlhokomelo e tlaase ho pholletsa le mefuta e mengata ea maemo a tshebetso. Kaho ea eona e tiisitsoeng le matšeliso a boikhethelo a mocheso li netefatsa hore li baloa ka mokhoa o tsitsitseng esita le maemong a feto-fetohang, e leng se etsang hore e be ntlafatso e fapaneng ho tsoa ho liphuputso tsa mokhoa oa laboratori bakeng sa ts'ebeliso e tsoelang pele ea indasteri.
Elektrode ea polasetiki ea pH sensor e sebetsa joang?
Setšoantšo sa SUP-PH5019pH sensor ea metsie sebetsa joalo ka sensor ea potentiometric ho tekanyo ea boleng ba pH. Taba ea pele, lesela le tšesaane la khalase le utloang pH le hlahisa voltage e lekanang le phapang ea tšebetso ea hydrogen ion lipakeng tsa buffer e ka hare (pH e tsitsitseng) le tharollo ea ts'ebetso ea kantle.
Joale, electrode e tsitsitseng ea litšupiso, e tlatsitsoeng ka gel ea KCl 'me e kopantsoe ka borokho ba letsoai la PTFE e nang le porous, e fana ka monyetla oa kamehla oa ho bapisa.Phapano ena e ka bang teng, eo hangata e leng 59.16 mV ka yuniti ea pH ho 25°C, e lekanngoa le ho fetoloa ke transmitter ho boleng ba pH.
Qetellong, thermistor e hahelletsoeng ka har'a NTC10K ka bo eona e lefella litlamorao tsa mocheso letsoapong le ntlha ea zero, e netefatsa ho nepahala ho pholletsa le sebaka sa ts'ebetso, le karabelo ka lipalo tse nepahetseng tsa pH.
Lintlha tse ka sehloohong
Sensor ea pH ea liindasteri ea SUP-PH5019 e hlahella ka boenjiniere ba eona bo sebetsang bo leka-lekaneng ts'ebetso, ho tšoarella, le ho khoneha maemong a boima:
- Matlo a Plastiki a Mathata- Polima e fetotsoeng ea mocheso o phahameng e hanana le kutu e matla ea asiti / alkali le ts'usumetso ea mochini ho feta 'mele oa khalase.
- Referense ea Habeli-Junction- Porous PTFE diaphragm e fokotsa tšilafalo le ho lelefatsa bophelo ba ts'ebeletso ka tharollo e litšila kapa ea pula.
- Gel Electrolyte- Ha e na tlhokomelo, ha ho hlokahale ho tlatsa hape; e fokotsa ho dutla le ho hoholeha.
- Matšeliso a Mocheso o Kopanetsoeng- Karolo ea NTC10K bakeng sa tokiso ea othomathiki, ho ntlafatsa ho nepahala lits'ebetsong tse fapaneng tsa mocheso.
- Karabelo e potlakileng le e tsitsitseng- Ho hanyetsa ka hare ho tlase (<250 MΩ) le letsoapo le phahameng (> 98%) li fana ka 'malo o potlakileng, o phetoang.
- Kenyelletso e Bonolo- E tloaelehileng 3/4 ″ NPT e rokang holimo le tlase; PG13.5 boikhethelo; Cable ea limithara tse 5–10 e nang le sehokelo sa BNC.
- Mamello ea Khatello le Mocheso- Ho fihla ho 6 bar le 80 ° C ts'ebetso e tsoelang pele.
