Product details
Lovibond COD analyzer
Measurement range: 0 to 150 mg/L (ppm) O2, 0 to 1500 mg/L (ppm) O2, 0 to 15000 mg/L (ppm) O2
Detection principle: The potassium dichromate method (K2CrO7) is used to determine the chemical oxygen demand (COD). The pre made COD reagent complies with the Standard Method 5220D and US EPA 410.4 standards. The dedicated heating digestion device is made of heat-resistant and corrosion-resistant materials, and can digest 24 samples simultaneously. It has overheating protection function to ensure safe and stable use.
Unique SMD microcomputer control technology, high-quality narrow band filter, temperature compensated LED optical system, built-in reaction timer to ensure consistency between sample measurement and user results, compact overall design, waterproof sample pool to ensure fast and accurate measurement, good reproducibility, calibration function and built-in software adjustment function, applied in scientific research, metrology for sample testing and identification.
Equipped with unique SMD microcomputer control technology, high-performance narrowband filter and temperature compensated LED light source system, new waterproof design, exquisite portability, and background light display screen.
▷ Factory and user-defined dual calibration function, automatic memory of the last zero calibration, no need for frequent zero calibration, good GLP function, automatic shutdown setting.
Unique IRiM infrared data transmitter [recommended ET214050] design, 16 sets of data storage, can be accessed and read at any time, convenient for on-site data organization and recording, and easy to connect with a computer for data transmission.
