TDCM-101 CODMn tester

The TDCM-101 CODMn analyzer is designed for accurate and efficient measurement of Chemical Oxygen Demand (COD) in water samples. The instrument features a wide measurement range of 0 to 10 mg/L, with the capability to measure higher concentrations after sample dilution, making it suitable for various environmental and industrial applications. Its minimum detection limit is as low as 0.20 mg/L, ensuring high sensitivity for trace analysis. The device offers a resolution of 0.01 mg/L, allowing precise readings even at low concentrations. The indication error is within ±4%, and the repeatability is better than 3%, guaranteeing reliable and consistent results. The analyzer performs digestion at a controlled temperature of 100°C ± 1.5°C, with a digestion time of 30 minutes, ensuring complete reaction of the sample. The optical system is highly stable, with an absorbance drift of less than 0.002 A within 20 minutes, ensuring accurate and stable measurements over time. The compact design of the host unit measures 266 mm × 200 mm × 130 mm, and the total weight is approximately 1 kg, making it easy to handle and install in different environments. This analyzer is ideal for laboratories, water treatment plants, and field applications where portability and performance are essential.
