Overview
TONGAO TR 6900D desktop STIP-scan can quickly determine COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, suspended solids and other parameters in various water quality. The instrument integrates mature technology in the field of water quality analysis, making the entire analysis system more complete, the operation is simpler and faster, and the detection results are more stable and reliable.
Features
1. Built-in two COD detection methods: HJ/T399-2007 (national standard) and import detection method
2. Standard test parameters include COD (prefabricated reagent), COD (powder pack reagent or custom reagent), ammonia nitrogen, total phosphorus, turbidity, suspended solids
3. Strong scalability in the later stage, can expand parameters such as total nitrogen, phosphoric acid salt, total chromium, hexavalent chromium, iron, nickel, zinc, copper and so on
4. Colorimetric digestion tube is used for operation, sample digestion and result reading share a reaction tube
5. Display the test results directly, and the system converts the Absorption measurement into the sample concentration value by a specific algorithm
6. Conduct 10 or more measurements of water samples, and take the average value after excluding abnormal values
7. With the function of detecting abnormal prompts, such as blank comparison prompts, and results exceeding the upper limit of the range prompts
8. Built-in thermal printer, data storage 30,000 records
9. Support 16/25 water samples/batch processing
Principle
The instrument uses a digestion Colorimetric integrated tube for operation, and the digestion and result reading of the sample share a reaction tube, eliminating the need to transfer the liquid to the Colorimetric dish for detection. Absorption measurement is performed on the sample using a cold light source of a specific wavelength, and the instrument system directly converts the detection results into sample concentration values through a specific algorithm. Water samples are measured 10 times or more, and the average value is taken after removing the abnormal value to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the results.
Applications
Emergency monitoring, industrial wastewater, domestic sewage, sewage treatment, chemical industry, food, beverage, Spinning & weaving printing and dyeing, Eletroplating, papermaking, petroleum metallurgy, river treatment, R & D institutions, colleges and universities
Standards
HJ/T399-2007、HJ535-2009、GB11893-89
Steps
1. Sample Handling with Digestion Colorimetric Tube
2. 10 or more measurements of water samples
3. The instrument automatically removes abnormal values and takes the average value.
4. The system directly converts the test results into sample concentration values and displays
5. Instrument prompts to detect abnormal conditions
Notice
• Pay attention to detecting abnormal prompts, such as blank comparison prompts, and results exceeding the upper limit of the range prompts
• Avoid using dirty, scratched, fingerprints or defective glass tubes
• Ensure that it is used under the specified environment conditions: environment humidity ≤ 85% without condensation, environment temperature 5~ 40 ℃
• Use the correct power supply method: AC (220V +/- 10%), 50Hz
