Introduce
The instrument has perfect functions and high accuracy. It can be used for rapid determination of COD, total phosphorus, total nitrogen, ammonia nitrogen, turbidity and other parameters in drinking water, surface water, groundwater, landscape water, industrial wastewater, medical and urban sewage and other water bodies. Adopt grating spectrometer system, equipped with multi-function software, can replace spectrophotometer, realize multi-purpose of one machine.
•Microcomputer precision type, all Chinese operation interface. Large-screen LCD with backlight LCD display clearly displays clock, parameters, data, units, status prompts, etc.;
•Equipped with micro-power chips, large-capacity memory, and high-precision clock chips. Equipped with a USB interface, it can be connected to a •PC computer and a micro-printer. Optional PC software;
•At most 30-360 groups of working standard curves can be selected, which can be used directly. Automatic parameter selection, more than 100 water quality parameters to choose from.
•There are four working modes: T, A, C, F. Up to 7 points of automatic non-linear concentration calibration in C mode.
1000 sets of test data can be stored arbitrarily. It has the function of self-diagnosis error code prompt function, and has the function of saving after a power failure;
•A reliable positioning structure and independent multi-optical path detection system can effectively avoid the interference caused by stray light, and can accurately measure the ion concentration value in the sample;
•The complete set is equipped with a digestion furnace, the digestion temperature and time can be set at will, the microcomputer heating temperature control system, and the over-temperature protection function can effectively save energy consumption;
•Self-developed rapid digestion reagents ensure long-term stable and low-cost supply, effectively reduce user workload and sample testing costs, and meet national standards.
