Product Description CL-2058-01 Industrial Online Chlorine ElectrodeTechnical Indexes Measuring range:0.005 ~ 20ppm(mg/L) HOClThe minimum detection limit:5ppb or 0.05mg/L HOClAccuracy:2% or ±10ppbHOCl response time:90%<90secondStorage temperature:-20 ~ 60 oCOperation temperature:0~45oC Sample temperature:0~45oC Calibration method:laboratory comparison methodCalibration interval:1/2 monthMaintenance interval:Replacement of a membrane and electrolyte every six monthsThe connection tubes for inlet and outlet water:external diameter Φ10Working principleElectrolyte and osmotic membrane separates the electrolytic cell and water samples, permeable membranes can selectively to ClO- penetration;between the two electrode has a fixed potential difference, current intensity generated can be converted into residual chlorine concentration;At the cathode: ClO- + 2H+ + 2e- → Cl-+ H2OAt the anode: Cl- + Ag → AgCl + e- Because in a certain temperature and pH conditions, HOCl, ClO- and residual chlorine between fixed conversion relationship,in this way can measure the residual chlorine.FAQQ: Are you trading company or manufacturer ?A: We are factory.Q: How long is your delivery time?A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock,it is according to quantity.Q: Do you provide samples ? is it free or extra ?A: We can offer the sample, it is extraQ: What is your terms of payment ?A: 100% T/T in advance ,balance before shippment.
