Overview
TR 6900CN desktop STIP-scan is a high-efficiency water quality analysis instrument launched by TONGAO, which can quickly determine COD, total nitrogen and other parameters in water. It integrates mature water quality analysis technology to make the system more perfect, the operation is simple and fast, and the detection results are 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: the first method conforms to the HJ/T399-2007 national standard, and the second method adopts the imported detection method.
2. Standard test parameters include COD (prefabricated reagent), COD (powder pack reagent or custom reagent), and total nitrogen (TN).
3. Strong scalability in the later stage, support ammonia nitrogen, phosphoric acid salt, total phosphorus, CODmn, turbidity, suspended solids (SS), total chromium, hexavalent chromium, copper, iron, nickel, zinc and other parameters.
4. Colorimetric digestion tube is used, and a reaction tube is used for digestion and result reading without transferring liquid.
5. Direct display results, Absorbance measurement by a specific wavelength cold light source, the system algorithm directly converts the concentration value.
6. Multiple measurements and removal of abnormal values, 10 or more measurements of water samples, after removing abnormal values, take the average value to reduce external interference.
7. Detect abnormal prompt function, including blank comparison prompt and result overrange upper limit prompt.

High Accuracy Specifications: Measurement Error ≤ +/- 5%, Repeatability ≤ +/- 5%, Optical inspection Stability ≤ +/- 0.001A/20min, Data storage 30,000 records, Linear dispersion 96 expandable, built-in thermal printer, 5-inch high-definition color LCD screen, batch processing capacity 16/25 water samples/batch.
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 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. 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. At the same time, provide detection anomalies, such as blank comparison prompts and results exceeding the range limit prompts.
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. Sample Handling is performed using a digestion Colorimetric tube, and digestion and result reading are completed in the same reaction tube.
2. The instrument automatically uses a specific wavelength cold light source to measure sample Absorbance.
3. The system algorithm converts the Absorption value directly to the concentration value and displays the result.
4. Perform multiple measurements (10 times or more) on the water sample, remove the abnormal value and take the average value.
5. The instrument prompts to detect abnormal conditions, such as blank contrast or over-range.
Notice
• Avoid dirt, scratches, fingerprints or glass tube imperfections when using digestion Colorimetric tubes to reduce measurement errors.
• Pay attention to detecting abnormal prompts, and deal with blank comparisons and overruns in a timely manner.
• Ensure that the operating environment humidity is ≤ 85% without condensation, and the temperature is within the range of 5~ 40 ° C.
• Power supply mode is AC (220V +/- 10%), 50Hz, to avoid voltage fluctuations affecting instrument performance.
• Instrument Protection Rating is IP30, pay attention to dust and slight water splash when using.
