Overview
TR 6900DZ desktop STIP-scan is a multi-functional water quality analysis instrument launched by TONGAO, which can quickly determine COD, ammonia nitrogen, total phosphorus, total nitrogen and various heavy metals (total chromium, hexavalent chromium, copper, zinc, nickel, iron) and other parameters. The instrument integrates mature technology in the field of water quality analysis, simple and fast operation, stable and reliable detection results, and is 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 and colleges and other fields.
Features
1. Built-in two COD detection methods, respectively in line with 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, total nitrogen and heavy metals
3. Strong scalability in the later stage, support phosphoric acid salt, nitrite, residual chlorine/total chlorine, manganese method COD, nitrate nitrogen, fluoride and other parameters
4. Adopt digestion Colorimetric integrated tube design, digestion and Colorimetric share the same reaction tube, no liquid transfer required
5. Built-in thermal printer and 5-inch high-definition color LCD screen
6. Support batch processing, each batch can handle 16/25 water samples
7. data storage capacity up to 30,000 records, including item, date, time, sample ID and other information
8. Optical inspection Stability, light source life of 100,000 hours
Principle
The instrument uses a digestion Colorimetric integrated tube for operation, and the digestion and result reading of the sample share a reaction tube. Absorbance measurement of the sample through a specific wavelength cold light source, the system directly converts the detection results into concentration values through a specific algorithm. Perform 10 or more measurements on the water sample, remove the abnormal value and take the average value to reduce the influence of dirt, scratches, fingerprints or glass tube defects on the results. The system has the function of detecting abnormal prompts, 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
Standards
HJ/T399-2007、HJ535-2009、GB11893-89、GB7466-87、GB7467-87、GB11910-89、HJ/T345-2007
Steps
1. Sample Handling Using Digestion Colorimetric Tubes
2. Put the reaction tube into the instrument for testing
3. Absorbance measurement and concentration calculation
4. The system makes multiple measurements and removes outliers
5. Directly read the test results
6. Reports can be output through the built-in printer
Notice
• Instrument ambient temperature range is 5~ 40 ℃, humidity ≤ 85% non-condensing
• Power requirements are AC 220V +/- 10%, 50Hz
• Pay attention to the digestion environment requirements of different parameters (such as COD needs to be digested at 165 ° C for 15-20 minutes, and total phosphorus needs to be digested at 125 ° C for 30 minutes)
• Some parameters do not need to be digested (e.g. ammonia nitrogen, hexavalent chromium, copper, nickel, zinc, iron)
• Measurement range and detection limit of each parameter
• Pay attention to the instrument during use Protection Rating is IP30
• Stability of Optical inspection system
