COD[http://www.delin.cn] Analyzer Measurement Range: (0.0～100.0)mg/L (basic measurement range), (100.0～1000)mg/L. Instrument basic error: ±2% (FS). Instrument repeatability: no more than 1% (FS). Electrolytic current is divided into three levels: 10mA, 20mA, 40mA. Normal operating conditions of the instrument: a) Ambient temperature: (5.0～35.0)℃; b) Relative humidity: no more than 85%; c) Power supply: AC(220±22)V, frequency (50±0.5)Hz; d) No corrosive gases in the surrounding air; no vibration affecting performance; no electromagnetic interference affecting performance other than the earth's magnetic field.
Purpose of COD Analyzer: The COD-572 type Chemical Oxygen Demand Analyzer uses coulometric titration for measurement. This method is simple, fast, uses fewer reagents, and simplifies the steps using standard solutions. It is especially suitable for industrial wastewater control analysis in mining enterprises and can also be used by environmental monitoring departments for measuring chemical oxygen demand in water quality.
