Multi parameter water quality analyzer

Multi parameter water quality analyzerAll testing items comply with the national industry standards: COD - "HJ/T399-2007", ammonia nitrogen - "HJ535-2009", total phosphorus - "GB11893-89" according to the technical requirements and detection methods of HJ 924-2017 COD photometric rapid determination instrument

Multi parameter water quality analyzerFeatures

1. More than 50 parameter indicators: directly measure multiple indicators such as chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, total nitrogen, suspended solids, chromaticity (platinum cobalt color system), turbidity, heavy metals, organic pollutants, and inorganic pollutants, with direct concentration reading;

2. Standard digestion instrument: Equipped with a 30 hole dual temperature zone multi parameter digestion instrument, it can simultaneously digest water samples with two different temperature indicators and meet the needs of users for large-scale sample testing, saving time;

3. Memory curve: There are 228 curves in memory, including 165 standard curves and 63 regression curves, which can be called as needed;

4. Data storage: It can accurately store 12000 measurement data (each data information includes detection date, detection time, instrument parameters at the time of detection, and detection results);

5. Data transmission: It can transfer current data and all stored historical data to the computer, supporting USB transmission and infrared wireless transmission (optional);

6. Intelligent constant temperature: The digestion power is automatically adjusted according to the number of loads, achieving intelligent constant temperature control and having functions such as delay protection;

7. Calibration function: The instrument comes with its own calibration function, which can calculate and store curves based on standard samples without the need for manual curve creation;

8. Built in printer: The instrument has a built-in printer that can print current data and all stored historical data.
