Product Description T9008 BOD Water Quality On-line Automatic MonitorProduct Principle:Water sample, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as a catalyst to join can more effectively straight-chain fatty compound oxide) and sulfuric acid mixture is heated to 175 oC, dichromate ion oxide solution of organic matter after color change, analyzer to detect the changes in color, and the change of conversion into BOD value output and consumption of dichromate ion content of oxidizable organic matter quantity.3.Technical Parameters:No.NameTechnical Parameters1Application RangeThis product is suitable for wastewater with chemical oxygen demand in the range of 10~2000mg/L and chloride concentration lower than 2.5g/L Cl-. It can be extended to wastewater with chloride concentration lower than 20g/L Cl- according to customers' actual demand.2Test MethodsPotassium dichromate was digested at high temperature and colorimetric determination.3Measuring range10~2000mg/L4Lower limit of Detection35Resolution0.16Accuracy±10% or ±8mg/L(Take the bigger value)7Repeatability10% or 6mg/L(Take the bigger value)8Zero Drift±5mg/L9Span Drift10%10Measurement cycleMinimum 20 minutes. Depending on the actual water sample, the digestion time can be set from 5 to 120min.11Sampling periodTime interval (adjustable), integral hour or trigger measurement mode can be set.12Calibration cycleAutomatic calibration (1-99 days adjustable), according to actual water samples, manual calibration can be set.13Maintenance cycleMaintenance interval is more than one month, about 30 minutes each time.14Human-machine operationTouch screen display and instruction input.15Self checking protectionWorking status is self-diagnostic, abnormal or power failure will not lose data. Automatically eliminates residual reactants and resumes work after abnormal reset or power failure.16Data storageNo less than half a year data storage17Input interfaceSwitch quantity18Output interfaceTwo RS232 digital output, One 4-20mA analog output19Working ConditionsWorking indoors; temperature 5-28oC; relative humidity≤90% (no condensation,no dew)20Power Supply and ConsumptionAC230±10%V, 50~60Hz, 5A21DimensionsHeight1500×Width 550×Depth 450(mm)After Sales Service* The warranty period is 12 months from commissioning acceptance date on.
