Introduction to the instrument
This is a spectrophotometer with established standard curves for water quality testing. It can support to detect indicators such as COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, heavy metals, fluoride, sulfide, sulfate, etc. in water.
Features
1. It can test about 50 indicators, such as chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, total nitrogen, free chlorine and total chlorine, suspended solid, chroma (platinum-cobalt color series), turbidity, heavy metal, organic pollutants and inorganic pollution. A number of indicators such as objects, direct reading of concentration;
2. Memory curve: 228 curves are stored in memory, including 165 standard curves and 63 regression curves. The corresponding curves can be called as needed;
3. Data storage: 12,000 measurement data can be stored accurately (each piece of data information includes the test date, test time, test 1, hour instrument parameters, test results);
4. Data transmission: can transmit current data and all stored historical data to the computer, support USB transmission, infrared wireless transmission (optional);
5. Intelligent constant temperature: the digestion power is automatically adjusted with the number of loads to realize intelligent constant temperature control with delay protection and other functions;
6. Calibration function: The instrument has its own calibration function, which can calculate and store the curve based on the standard sample, without the need to manually make the curve;
7. Built-in printer: The built-in printer of the instrument can print current data and all stored historical data.
