Brief introduction: Cyanide on-line automatic analyzer used to heating water with tartaric acid and zinc nitrate distillation, simple cyanide in water samples and some complex cyanide in the form of hydrogen cyanide is distilled out, by sodium hydroxide absorption after T with cyanogen amine to produce the hydrogen chloride, is the developer isonicotinic acid - pyrazolone reaction generated red intermediate, red intermediate generated rapidly, in had maximum absorption wavelength of 546 nm, and stable in a certain time. This product is a single factor parameter test and analysis instrument. This method is suitable for the cyanide in waste water within the scope of 0 ~ 1 mg/L. Technical parameters: Measuring range: 0 ~ 1 mg/L Detection limit: 0.05 Resolution: 0.001 Accuracy: + 10% or + / - 0.1 mg/L (both in the larger value) Repeatability: 10%, or 0.1 mg/L (both in the larger value) Zero drift: + / - 0.05 Span drift: 10% The measurement cycle: minimum test cycle 20 min Sampling period: the time interval (adjustable), the top of the hour, or trigger measurement mode, can be set up Calibration cycle: automatic calibration (adjustable) 1 ~ 99 days, according to the actual sample, can be set to manual calibration Data is stored data storage: not less than six months The input interface: switch quantity RS232 output interface: 1 road digital output, 2 road 4 ~ 20 ma analog output Working environment: indoor work, it is recommended that the temperature 5 ~ 28 ℃, humidity is 90% or less (condensation) Power supply and power consumption: AC230 plus or minus 10% V, 50 ~ 60 hz, 5 a Size: 1500 * 550 * 450 (mm)
