TDCM-101 CODMn tester

The TDCM-101 CODMn Analyzer is a high-performance instrument designed for the accurate measurement of Chemical Oxygen Demand (COD) in water samples. Its measurement range spans from 0 to 10 mg/L, with the capability to analyze diluted samples as well, making it highly versatile for various applications. The minimum detection limit is as low as 0.20 mg/L, ensuring sensitivity even for trace levels of organic matter. The instrument offers a resolution of 0.01 mg/L, allowing for precise and detailed readings. The indication error is within ±4%, ensuring reliable and consistent results. The repeatability of the device is less than 3%, demonstrating its stability and accuracy across multiple measurements. The digestion process takes place at a controlled temperature of 100°C ± 1.5°C, ensuring uniform reaction conditions. The digestion time is set at 30 minutes, optimizing the oxidation of organic compounds without excessive energy consumption. The optical system features excellent stability, with an absorbance drift of less than 0.002 A within 20 minutes, ensuring long-term measurement reliability. The host unit has dimensions of 266 mm × 200 mm × 130 mm, making it compact and suitable for laboratory or field use. The total weight of the device is only 1 kg, enhancing portability and ease of handling. This analyzer is ideal for environmental monitoring, wastewater treatment, and research laboratories requiring fast and accurate COD analysis.
