Cov qauv yuav tsum tau kuaj tsis tas yuav tsum tau pretreatment.Cov dej qauv riser yog ncaj qha tso rau hauv cov qauv dej, thiab tag nrho cov phosphorus concentration tuaj yeem ntsuas tau.Qhov kev ntsuas siab tshaj plaws ntawm cov cuab yeej no yog 0.1 ~ 500mg / L TP.Txoj kev no yog siv rau hauv online tsis siv neeg saib xyuas ntawm tag nrho cov phosphorus concentration ntawm pov tseg (s dej phwj) dej paug qhov chaw, dej nto, thiab lwm yam.
Cov txheej txheem | National Standard GB11893-89 "Dej zoo - Kev txiav txim siab ntawm tag nrho phosphorus Ammonium molybdate spectrophotometric method". | |
Kev ntsuas ntau | 0-500mg/L TP (0-2mg/L; 0.1-10mg/L; 0.5-50mg/L; 1-100mg/L; 5-500mg/L) | |
Qhov tseeb | tsis ntau tshaj ± 10% lossis tsis ntau tshaj ± 0.2mg / L | |
Rov ua dua | tsis ntau tshaj ± 5% lossis tsis ntau tshaj ± 0.2 mg / L | |
Lub sijhawm ntsuas | Lub sij hawm ntsuas qhov tsawg kawg nkaus ntawm 30 min, raws li cov qauv dej tiag tiag, tuaj yeem hloov kho ntawm 5 ~ 120min arbitrary digestion lub sij hawm. | |
Lub sijhawm ua piv txwv | lub sij hawm ncua sij hawm (10 ~ 9999min adjustable) thiab tag nrho cov ntsiab lus ntawm kev ntsuas hom. | |
Calibration lub sij hawm | 1 ~ 99 hnub, txhua lub sijhawm, txhua lub sijhawm kho tau. | |
Lub sijhawm tu | ib hlis ib zaug, txhua txog 30 min. | |
Reagent rau kev tswj hwm tus nqi | Tsawg dua 3 yuan / qauv. | |
Tso zis | RS-232; RS485; 4 ~ 20mA peb txoj kev | |
Kev xav tau ib puag ncig | kub adjustable sab hauv, nws pom zoo kub 5 ~ 28 ℃ ; humidity ≤ 90% (tsis muaj condensing) | |
Fais fab mov | AC230 ± 10% V, 50 ± 10% Hz, 5A | |
Loj | 1570 x 500 x 450mm (H * W * D). | |
Lwm tus | lub tswb txawv txav thiab lub zog tsis ua haujlwm yuav tsis poob cov ntaub ntawv; |
Kov npo zaub thiab hais kom ua input
Kev hloov pauv tsis zoo thiab lub hwj chim tawm tom qab hu, lub cuab yeej cia li tso tawm cov residual reactants nyob rau hauv lub ntsuas, rov qab mus ua hauj lwm.
