AQUA water quality measuring device COD automatic measuring device (reagent small quantity specification) COD-380R
Anatec Yanaco Co., Ltd.
About This Product
An automated device that measures COD (Chemical Oxygen Consumption), an important parameter for knowing the water quality of river water or industrial wastewater, based on the Japanese Industrial Standard JIS K0102 (Industrial Wastewater Testing Method) and Sewage Testing Method. is. While maintaining the maintainability and measurement performance of the previous model, it is now equipped with an LCD touch panel, schedule measurement function, etc. Additionally, the amount of reagents required for measurement is halved compared to ours, reducing reagent running costs.
■Features
・The boiling water circulation method enables measurement under the same heating temperature conditions as the JIS method, providing highly reliable measurement values.
- End point detection uses a unique low current polarization potential difference method that can differentially detect redox potential, allowing accurate end point detection.
・In addition to data printing such as measured values and measured value bar graphs, it also has a self-diagnosis function that prints out abnormalities in the device.
- Reduced reagent consumption to 1/2 compared to our company.
■Repeatability (with standard solution)
・Full scale ±1% (for measurement range 20mg/L)
・Full scale ±2% (for measurement ranges exceeding 20mg/L and below 200mg/L)
・Full scale ±3% (when measuring range exceeds 200mg/L)
*For two-step dilution measurement, full scale ±4%...Option
■Stability
・Both zero and span drift (in 24 hours)
・Full scale ±3% (for measurement range 20mg/L to 200mg/L or less)
・Full scale ±4% (when measuring range exceeds 200mg/L)
*For two-step dilution measurement, full scale ±5%...Option
■Installation space
Maintenance space of 1m in front and approximately 0.6m in rear is required.
