CL-201 Colorimetric Residual Chlorine Analyzer

Measurement principle:Using DPD colorimetric method to detect the concentration of residual chlorine which is an measurement accurate, cost-effective and low maintenance instrument. It is suitable for the measurement of residual chlorine in chlorine disinfection process and monitoring of residual chlorine concentration in drinking water pipe network. Continuous operation 30 days of reagent dosage, realize unattended operation, operation and maintenance cost is low.Features:①The DPD standard colorimetric method②The continuous operation of 30 days do not need to replace the reagent, simple operation, low operation and maintenance cost③Two programmable relay, can set the concentration alarm④It is suitable for measuring residual chlorine in tap water, circulating cooling water, sewage chlorination process of residual chlorine measurement and tap water pipe network.Technical IndexesMeasure range 0~5ppmAccuracy ±5% reading or ±0.03ppm Cl2，take bigDetection limit 0.03mg/LDisplay 70mm×48 mm LCDCalibration Use default calibration curvesOperation condition Sample flow rate: 200-400mL/minSample inlet pressure: 0.1~5barSample temperature:5~40℃Power supply 220-230VAC，50/60HzOutput 4-20mARelay Two groups of relays, can set the concentration alarmStorage temperature range -40～60℃Storage humidity humidity：10-90%, non condensingSize 460mm*350mm*186mm（L*W*H）Weight About 9KGInstallation Wall hanging
