Online COD Analyzer
Detection Principle
Wedzera huwandu hunozivikanwa hwe potassium dichromate mhinduro kumuenzaniso wemvura, uye shandisa munyu wesirivha sechinhu chinokonzera uye mercury sulfate se masking agent mune yakasimba acid medium. Mushure mepamusoro-tembiricha uye yakanyanya-kudzvanywa digestion reaction, tarisa kunyura kwechigadzirwa pane imwe wavelength. Zvinoenderana nemutemo weLambert Beer, pane mutsara kuwirirana pakati pemakemikari okisijeni anodiwa ari mumvura uye kunyura, uyezve kuona kusanganiswa kwemakemikari okisijeni kudiwa mumvura.Cherechedza: Pane zvakaoma kuisa oxidize zvinhu zvakadai seanonhuhwirira hydrocarbons uye pyridine mumvura sampuli, uye nguva yekugaya inogona kuwedzerwa zvakakodzera.

Hunhu
1. Iyo analyzer ndeye miniaturization muhukuru, iyo yakanakira kugadzirisa kwezuva nezuva;
2. High-precision photoelectric metering uye yekuongorora teknolojia inoshandiswa kugadzirisa kune dzakasiyana-siyana dzakaoma miviri yemvura;
3.Matatu matatu (0-100mg / L), (0-200mg / L) uye (0-1000mg / L) anogutsa zvakawanda zvehutano hwemvura hunodiwa. Rwendo runogonawo kuwedzerwa maererano nemamiriro chaiwo;
4. Fixed-point, periodic, kuchengetedza uye mamwe maitiro ekuyera anogutsa zvinodiwa zvekuyera frequency;
5.Inoderedza mari yekushanda nekugadzirisa nekuderera kwekushandisa reagents;
6. 4-20mA, RS232/RS485nedzimwe nzira dzekukurukurirana dzinogutsa zvinodiwa pakutaurirana;
Applications
Iyi analyzer inonyanya kushandiswa kune chaiyo-nguva yekutarisa kemikari oksijeni
