Technical Specifications

Standard Configuration

Data download

-It can directly test COD, ammonia nitrogen, total phosphorus and total nitrogen; it can expand many indexes, such as chromaticity, turbidity and heavy metals and so on

-Chinese operating interface, large screen guidance menu liquid crystal display

-Full-automatic wave length, intellectualized design, automatic calibration after starting-up

-Tungsten lamp and deuterium lamp were independently controlled, which can prolong the life of deuterium lamp

-The instrument can calculate and store curve based on standard samples

-Among the built-in 100 curves, 30 standard curves do not need to adjust, can use directly, and other curves can automatically repair and store

-Built-in printer and USB interface can connect the computer making online operation (optional)

-It has the function of top-grade UV-light spectrophotometer

-Blowout control cover of digest instrument adopts materials with transparency, heat resistance and acid and alkali resistance, so it is safe and reliable

-Dual-temperature area can digest two indexes of water samples with different temperature at the same time, which can save time

-It has the functions of setting temperature, modifying timekeeping operating line and storing data

-It can adjust and store temperature and time at will
