Overview
The TR 6900Z desktop STIP-scan is an integrated heavy metals measuring instrument produced by TONGAO, which can quickly determine the parameters of total chromium, hexavalent chromium, copper, nickel, zinc, iron and other parameters in water. The instrument integrates mature technology in the field of water quality analysis, making the analysis system more complete, simple and fast operation, and stable and reliable detection results.
Features
1. Built-in two COD detection methods: HJ/T399-2007 national standard method 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, heavy metals
3. Strong scalability in the later stage, can expand 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 a reaction tube
5. Built-in thermal printer and 5-inch high-definition color LCD screen
6. Data storage capacity 30,000 records, support 96 Linear dispersion
7. Support 16/25 water sample batches
Principle
1. The digestion Colorimetric integrated tube is used for operation. The digestion of the sample and the reading of the result share a reaction tube, and there is no need to transfer the liquid. 2. Absorbance measurement is carried out on the sample with a cold light source of a specific wavelength, and the detection result is directly converted into the sample concentration value through a specific algorithm. 3. The water sample is measured 10 times or more, and the average value is taken after excluding the abnormal value to reduce the influence of external factors on the result. 4. It has the function of detecting abnormal prompts, including blank comparison prompts and results over-range upper 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
GB7466-87、GB7467-87、GB11910-89、HJ/T345-2007、HJ/T399-2007
Steps
1. Sample Handling Using Digestion Colorimetric Tubes
2. Select the corresponding detection method according to the detection parameters
3. The instrument automatically performs multiple measurements and removes abnormal values
4. Directly read the concentration test results
5. The test report can be output through the built-in printer
Notice
• Blank comparison test is required before use
• Pay attention to the over-range prompt of the test results
• Ensure that the digestion Colorimetric integrated tube is clean and pollution-free
• Operating environment temperature should be kept within the range of 5~ 40 ℃
• environment humidity does not exceed 85% and no condensation
• Powered by AC 220V +/- 10% power supply
