Labtron COD Analyzer provide measurement of oxygen required to chemically oxidize organic and inorganic matter in water. They incorporate filtration unit to eliminate particulate interference and utilizes spectrophotometer to measure O2 demand in various samples. Their glass reaction vessels are designed for optimal mixing and accurate measurement. They implement advanced cooling system to maintain stable temperatures during testing process. Our COD Analyzer is ideal in pulp and paper industry, hydroponics and aquaponics, pharmaceuticals and beverage production.







Labtron’s COD Analyzer offers a wide measuring range (10 to 10,000 mg/L), a user-friendly interface, advanced calibration options, and high accuracy. It also has a large data storage capacity, supporting long-term monitoring and record-keeping. The integrated thermal printer allows for immediate printing of current and stored test data.
Yes, Labtron’s COD Analyzer features a 5-inch high-resolution touchscreen with a graphical user interface for easy operation. The COD Analyzer supports automatic measurements and can store up to 500 sets of test data.
Labtron’s COD Analyzer supports automatic measurements and provides direct concentration readings. Its built-in standard curve allows users to set up curves according to different measurement requirements. The COD Analyzer features a high-resolution touchscreen with a graphical user interface for easy operation but basic training is recommended for best results.
The COD Analyzer features a separate measurement and digestion device, enhancing optical stability during testing by isolating the optical system from digestion heat. The COD Analyzer features cold light source and a narrow-band interference optical system, providing excellent optical stability.
Our COD Analyzer offers continuous adjustment of both digestion temperature and time, allowing versatility in handling a wide range of samples. It is perfect for water analysis, wastewater treatment, environment monitoring, Industrial processing water and scientific research.
