Overview
TONGAO TR 6900CPN desktop STIP-scan can quickly determine COD, total phosphorus, total nitrogen, turbidity, suspended solids and other parameters in water. It integrates mature technologies in the field of water quality analysis, making the entire analysis system more perfect, the operation is simpler and faster, and the detection results are more stable and reliable. Widely used in 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 other fields.
Features
1. Built-in two COD detection methods: method one conforms to HJ/T399-2007 national standard, method two is imported detection method; 2. Standard detection parameters include COD (prefabricated reagent), COD (powder pack reagent or custom reagent), total phosphorus, total nitrogen, turbidity, suspended matter; 3. Strong scalability in the later stage, scalable parameters include ammonia nitrogen, total chromium, phosphoric acid salt, manganese method COD, hexavalent chromium, copper, iron, nickel, zinc, nitrite, etc.; 4. Colorimetric digestion tube is used, and a reaction tube is shared for sample digestion and result reading; 5. Direct display of detection results, the system converts Absorbance into concentration value through a specific algorithm; 6. Multiple measurements and removal of abnormal values to reduce interference effects; 7. Detection of abnormal prompts, such as blank comparison prompts, results over range upper limit prompts; 8. Built-in thermal printer and 5-inch high-definition color LCD screen; 9. Support USB data cable, LAN and other communication interfaces; 10. The operation interface supports membrane button operation, optional Chinese/English.
Principle
The instrument uses a digestion Colorimetric integrated tube for operation. The digestion and result reading of the sample share a reaction tube, and there is no need to transfer the liquid to the Colorimetric dish for detection. Absorption measurement is carried out on the sample with 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. Perform 10 or more measurements on the water sample, and take the average value after removing the abnormal value to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the results, and prompt the detection of abnormalities, such as blank comparison prompts, results exceeding the upper limit of the range prompt, etc.
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
Steps
1. Use the digestion Colorimetric integrated tube for Sample Handling; 2. Put the sample into the instrument for Absorbance measurement; 3. The instrument automatically performs multiple measurements and eliminates abnormal values; 4. The system calculates and directly displays the concentration results; 5. If there is any abnormality, the instrument will prompt blank comparison or overrange and other information.
Notice
• Pay attention to the environment temperature within the range of 5~ 40 ° C during operation; • environment humidity should be ≤ 85% without condensation; • Avoid dirt, scratches or fingerprints when using the digestion Colorimetric integrated tube; • Check the prompt information in time when detecting abnormalities; • Power supply mode is AC (220V +/- 10%), 50Hz to ensure stable power supply; • Instrument Protection Rating is IP30 to avoid use in harsh environments.
