Tshuaj Oxygen Demand Sensor (COD Sensor)|Online COD Digital Probe

Qhov kev lag luam hauv online Chemical Oxygen Demand (COD) sensor tau txais kev ntsuas qib siab UV absorption spectroscopy (UV254), nrog kev ua haujlwm ntawm cov teeb liab ua ke, ua tau -nyob rau hauv cov nyiaj kub thiab IP68 waterproof qauv. Nws muab tus qauv RS485 (Modbus-RTU) cov khoom tso tawm digital, muaj cov lus teb ceev ceev, reagent- ua haujlwm dawb, tsis tu ncua thiab ruaj khov siab. Nws yog dav siv nyob rau hauv cov dej saum npoo av, cov dej khib nyiab hauv nroog, kev lag luam effluent, aquaculture thiab cov txheej txheem dej xyuas, thiab tuaj yeem txuas seamlessly nrog PLC, DCS thiab MTW series controllers.

Qhov online COD sensor no yog ib qho kev sojntsuam ntse uas tsim los rau tiag tiag -lub sijhawm ntsuas cov pa phem hauv dej. Nws siv lub hauv paus ntsiab lus ntawm UV nqus spectroscopy (254nm), uas cuam tshuam txog UV nqus dej ntawm cov tshuaj lom neeg xav tau (COD), Total Organic Carbon (TOC) thiab lwm yam tsis muaj organic. Txoj kev kho qhov muag no yuav tsum tsis muaj cov tshuaj chemical reagents, tsis muaj cov txheej txheem zom zaub mov, thiab ua tiav qhov tiag -lub sijhawm saib xyuas online nrog lub sijhawm teb ntawm vib nas this, txo cov nqi khiav lag luam thiab ib puag ncig muaj kuab lom.

Lub qhov rais kho qhov muag yog ua los ntawm siab -lub zog sapphire nrog los tiv thaiv- fouling txheej, zoo txo cov kab mob thiab ua kom muaj kev ntsuas ruaj khov hauv ntau qhov chaw dej. Ua tau - nyob rau hauv qhov kub thiab txias sensor paub qhov kub tsis siv neeg them nyiaj, kho qhov ntsuas drift tshwm sim los ntawm kev hloov kub. Lub tshuab tag nrho txais yuav cov teeb liab txias thiab hluav taws xob cais tsim, muaj zog tiv thaiv -electromagnetic cuam tshuam muaj peev xwm, txhawb kev ruaj khov ntev -cov ntaub ntawv kis tau tus mob ntawm RS485 Modbus-RTU.

Lub tsev sojntsuam yog ua los ntawm corrosion-resistant PPS/PEEK engineering yas thiab 316L stainless hlau, haum rau ntev -lub sij hawm submerged installation nyob rau hauv industrial thiab ib puag ncig dej systems. Nws txhawb nqa cov txheej txheem daws teeb meem (phthalic acid potassium hydrogen standard tov), nrog rau cov ntaub ntawv ntsuas lub zog-tawm cia thiab ua txhaum tus kheej- kuaj mob ua haujlwm. Nws yog ib qho cuab yeej zoo tshaj plaws rau kev saib xyuas cov pa phem hauv cov organic, tswj kev ua raws cai thiab kev ua kom zoo.
