1. Introduction to the instrument

Comply with "HJ 924-2017 COD spectrophotometric rapid measuring instrument technical requirements and testing methods" All testing items are based on national industry standards: COD- "HJ/T399-2007", ammonia nitrogen-"HJ535-2009", total phosphorus-"GB11893-89".

2. Features

1. It can test about 38 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.
