QCOD-3F COD Rapid Tester Introduction: The product is digested using sealed catalysis followed by colorimetric measurement. The instrument adopts advanced cold light source, narrow-band interference technology and microcomputer to automatically process data, and directly display the COD (mg/L) value of the sample. The instrument is widely used in environmental monitoring, sewage treatment, colleges and universities, scientific research units and other departments Features: 1. The measuring instrument is separated from the digestion instrument, which does not affect the stability of the optical system. 2. The measuring instrument is a cold light source and a narrow-band interference optical system with good optical stability. 3. LCD large-screen LCD display in Chinese, easy to operate and intuitive. 4. The temperature of the digester is automatically controlled by PID and timing, with high precision. 5. The operation is simple and time-saving, and there is no need to change the tube for digestion and colorimetry. 6. The digestion temperature and time can be set steplessly for other purposes. 7. It can save 10 standard curves and 500 measured values, and it will not be lost after power failure. Technical parameter: Measuring range: 5～2000mg/L (over dilution determination) Repeatability: ≤±3% Temperature control system: room temperature~180℃ can be set, digestion temperature is 165℃ Temperature control time: 1~999min adjustable Optical stability: ≤0.002A/20min Indication error: ≤±8 % (F.S) Anti-chlorine interference: ≤2000mg/L Temperature control accuracy: ±0.5℃ Digestion time: 15min Batch volume: 12 water samples Ambient temperature: 5～40℃ Power supply: AC(220±22)V; (50±0.5)Hz Power consumption: <500W Instrument weight: Determination instrument: 3kg; Digestion instrument: 4kg Relative humidity: ≤85% Dimensions: Measuring instrument: 240mm×205mm×170mm; Digestion apparatus: 240mm×207mm×170mm
