Kev ua haujlwm thiab nta ntawm ammonia nitrogen electrode
1.To ntsuas los ntawm immersion ncaj qha ntawm kev sojntsuam yam tsis muaj sampling thiab pretreatment;
2.Tsis muaj tshuaj reagent thiab tsis muaj kuab paug thib ob;
3.Lub sij hawm teb luv luv thiab muaj kev ntsuas tas li;
4.Nrog kev tu tsis siv neeg txo qhov zaus ntawm kev saib xyuas;
5.Rov qab kev twb kev txuas tiv thaiv ntawm qhov zoo thiab tsis zoo ncej ntawm sensor fais fab mov;
6.Kev tiv thaiv ntawm RS485A / B davhlau ya nyob twg tsis ncaj ncees lawm txuas nrog lub hwj huam mov;
7.Optional wireless cov ntaub ntawv kis tau tus mob module
Kev sim ntawm on-line ammonia nitrogen txais cov ammonia gas sensing electrode txoj kev
NaOH tov yog ntxiv rau cov qauv ntawm cov dej thiab sib tov sib npaug, thiab kho tus nqi pH ntawm tus qauv tsis pub tsawg tshaj 12. Yog li, tag nrho cov ammonium ions hauv cov qauv raug hloov mus rau hauv gaseous NH3 thiab dawb ammonia nkag mus rau ammonia gas sensing electrode los ntawm semi-permeable membrane los koom nrog cov tshuaj tiv thaiv, uas hloov pH tus nqi ntawm cov electrolyte hauv electrode.Muaj kev sib raug zoo ntawm kev sib txawv ntawm tus nqi pH thiab qhov concentration ntawm NH3, uas tuaj yeem saj los ntawm cov electrode thiab hloov mus rau hauv cov concentration ntawm NH4-N los ntawm lub tshuab tswv tsev.
Replacement voj voog ntawm ammonia nitrogen electrode
Hloov lub voj voog ntawm cov electrode yuav txawv me ntsis raws li cov dej zoo.Piv txwv li, lub voj voog hloov ntawm cov electrode siv nyob rau hauv cov dej huv huv yog txawv ntawm cov electrode siv hauv cov dej phwj tuaj.Pom zoo hloov lub voj voog: ib zaug ib lub lim tiam;Hloov lub taub hau zaj duab xis tuaj yeem siv dua tom qab rov tsim dua tshiab.Cov kauj ruam rov ua dua tshiab: soak lub taub hau hloov ammonia nitrogen hauv citric acid (tshuaj daws) rau 48 teev, tom qab ntawd hauv dej huv rau lwm 48 teev, thiab tom qab ntawd muab tso rau hauv qhov chaw txias rau huab cua kom qhuav.Ntxiv cov nyiaj electrolyte: qaij lub electrode me ntsis thiab ntxiv cov electrolyte kom txog thaum nws puv 2/3 ntawm lub taub hau zaj duab xis, thiab tom qab ntawd ceev cov electrode.
Kev npaj ntawm ammonium ion electrode
1. Tshem lub hau tiv thaiv ntawm lub taub hau electrode.Lus Cim: Tsis txhob kov ib qho rhiab ntawm lub electrode nrog koj cov ntiv tes.
2. Rau ib qho electrode: ntxiv cov kev siv tshuaj rau qhov sib txuam siv electrode.
3. Rau cov kua ntxiv cov khoom siv hluav taws xob: ntxiv cov tshuaj siv rau hauv cov kab noj hniav siv thiab xyuas kom meej tias cov kua ntxiv qhov qhib qhib thaum lub sijhawm kuaj.
4. Rau cov uas tsis yog refillable composite electrode: siv kua yog gel thiab kaw.Tsis tas yuav tsum muaj kua filling.
5. Ntxuav cov electrode nrog dej deionized thiab nqus nws kom qhuav.Tsis txhob so.
6. Muab cov electrode tso rau ntawm tus tuav electrode.Ua ntej siv nws, raus rau pem hauv ntej kawg ntawm lub electrode nyob rau hauv dej deionized rau 10 feeb, thiab ces muab tso rau hauv diluted chloride ion tov rau 2 teev.
