WDet-5000CN cyanide water quality online analyzer Introduction: Under weak acid conditions, cyanide and chloramine T form chlorohydrides, which then react with isonicotinic acid to hydrolyze to form glutaraldehyde. Finally, under the action of barbituric acid, a purple blue compound is formed. Within a certain concentration range, chromaticity is directly proportional to the mass concentration of cyanide. Applied to environmental pollution source monitoring, industrial process water monitoring, urban sewage treatment, surface water monitoring, surface water monitoring, etc. Features: 1. Permeability measurement technology is not affected by chromaticity, suspended solids, and bubbles 2. Special design of flow channel and reagent ratio, high detection accuracy, and low LLOQ (0.05mg/L) 3. Adopting constant temperature fiber optic technology and light intensity compensation algorithm, with small drift during long-term operation 4. Low maintenance workload and cost 5. Self diagnosis function 6. Highly integrated valve terminals, each valve can be individually maintained, disassembled, and cleaned 7. Using a USB flash drive for software updates and data export is more convenient 8. Touch control of Android screen; Modular design; The backplane can work off the screen without being affected by misoperation 9. Quality control function, with parallel sample detection, standard sample validation, and standard sample recovery rate detection functions 10. Reverse control function: Automatically start the instrument through flow rate, pH value, and other methods 11. Store data for 10 years; Supports uploading two different protocols simultaneously Technical parameters: Determination method: Isonicotinic acid barbituric acid spectroscopy Range: 0.05-1/2/5mg/L Indication error: ± 10% Repeatability: ≤ 5% Zero drift: ± 5% F.S. Span drift: ± 5% F.S. Reagent: Standard reagents can produce 400 samples Environmental temperature: 5 ℃~45 ℃ Measurement interval: continuous, 1, 2, 3... 24 hours, or initiated through serial port Maintenance:<2 hours/month
