NO3- Sensor

Qhov no NO3- Sensor yog ib qho kev lag luam digital ion- xaiv electrode rau tiag tiag-lub sijhawm saib xyuas cov nitrate (NO3⁻) hauv dej. Nws txais siab -rhiab heev ion xaiv membrane tshuab, nrog tsis siv neeg kub them nyiaj, zoo txo kev cuam tshuam los ntawm lwm yam ions.

Ua -hauv digital kis tau tus mob nti, tus qauv RS485 Modbus-RTU tso zis, IP68 submersible tsim, 3/4 "NPT xov mounting. Haum rau kev kho dej phwj tuaj, dej saum npoo av, aquaculture, industrial process water and environmental water quality nitrate online detection.

NO₃⁻ (nitrate) sensor yog cov khoom siv hauv online saib xyuas dej zoo rau lub sijhawm ntsuas ntawm cov nitrate yaj (NO₃⁻) / nitrate nitrogen (NO₃⁻ N) hauv dej, dav siv hauv kev kho dej khib nyiab, dej haus, dej ntws, dej hauv dej thiab kev ua liaj ua teb. Nws hloov cov nitrate concentration rau hauv hluav taws xob / kho qhov muag teeb liab rau kev soj ntsuam tas li thiab cov ntaub ntawv xa mus.

NO3-Sensor siab-precision nitrate sensing membrane teb xaiv rau NO3⁻ ions, ua kom muaj peev xwm ruaj khov raws li Nernst kab zauv. Lub sensor hloov pauv cov teeb liab analog rau cov ntaub ntawv digital, paub txog kev sib kis mus ntev ntawm RS485 rau cov ntaub ntawv tau txais thiab kev tswj hwm.

Cov ntsiab cai ua haujlwm tseem ceeb

1. UV Absorption Method (Nrov tshaj plaws rau kev soj ntsuam online)
• Lub hauv paus ntsiab lus: Nitrate muaj zog nqus siab kawg ntawm 210–220 nm UV teeb; absorbance ua raws li Txoj Cai Beer Lambert (absorbance ∝ concentration). Kev kho dual wavelength (210 nm + 275} nm) tshem tawm kev cuam tshuam los ntawm cov organic teeb meem thiab turbidity.
• Qhov zoo: Tsis muaj reagents, tsis muaj kuab paug thib ob, cov lus teb ceev ceev, kev ruaj ntseg ntev, kev saib xyuas tsis tshua muaj siab, siab raug rau kev ntsuas qis.
• Kev txwv: Tsis tuaj yeem paub qhov NO₃⁻ ntawm NO₂⁻; cuam tshuam los ntawm siab turbidity / suspended solids (xav tau turbidity them).

2. Ion Selective Electrode (ISE) Txoj Kev
• Lub hauv paus ntsiab lus: Ib qho nitrate tshwj xeeb polymer/PVC daim nyias nyias ua kom muaj peev xwm sib txawv raws li lub logarithm ntawm NO₃⁻ concentration (Nernst equation). Yuav tsum tau siv cov khoom siv hluav taws xob thiab cov tshuaj chloride (Cl⁻ yog qhov cuam tshuam loj).
• Qhov zoo: Tus nqi qis, kev cog lus, kev ntsuas ion ncaj qha, tsim nyog rau kev siv portable / teb.
• Cov kev txwv: Nrawm dhau lub sijhawm, nquag ntsuas qhov xav tau, lub neej luv luv ntawm daim nyias nyias, nkag siab rau Cl⁻, pH thiab kub.

3. Kev ntub dej tshuaj / Colorimetric Method (laboratory / High Precision Analyzers)
• Lub hauv paus ntsiab lus: Cadmium txo qis + Griess reagent cov tshuaj tiv thaiv tsim cov khoom xim; absorbance ntsuas ntawm 540 nm rau tag nrho nitrate + nitrite.
• Qhov zoo: Cov neeg raug siab (ua raws li cov txheej txheem), kev cuam tshuam tsawg, tsim nyog rau kev soj ntsuam kab.
• Kev txwv: Xav tau cov tshuaj reagents, kev saib xyuas nyuaj, teb qeeb, tsis zoo rau kev xa mus online ntev.

Daim ntawv thov teb
