TONGAO TR 6900A multi-channel water quality rapid tester can quickly determine the chemical oxygen demand (COD) value in water. It integrates mature technology 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 universities and other fields.
1. Built-in two COD detection methods: method 1 conforms to HJ/T399-2007 national standard, method 2 is imported detection method 2. Standard test parameters include COD (prefabricated) and COD (powder pack) 3. Strong scalability in the later stage, support ammonia nitrogen, total phosphorus, total nitrogen, CODmn, suspended solids, turbidity, total chromium, hexavalent chromium, copper, iron, nickel, zinc and other parameters 4. Colorimetric digestion tube, digestion and result reading share a reaction tube, no need to transfer liquid 5. Display the detection results directly, and the system converts Absorbance into concentration value through a specific algorithm 6. Multiple measurements and removal of abnormal values, 10 or more measurements of water samples, remove abnormal values and take the average value 7. Detect abnormal prompt function, including blank comparison prompt and result overrange upper limit prompt 8. Built-in thermal printer and 5-inch high-definition color LCD screen 9. Support USB data cable and LAN communication interface 10. The operation interface supports membrane button operation, optional Chinese/English
The instrument uses a digestion Colorimetric integrated tube for operation. The digestion and result reading of the sample share a reaction tube, so 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. The water sample is 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. The system also has the function of detecting abnormal prompts, such as blank comparison prompts, results exceeding the range limit prompts, etc.
