Overview
The TR 6900CP desktop STIP-scan is produced by TONGAO, which can quickly determine COD, total phosphorus, turbidity, suspended solids and other parameters in water quality. The instrument integrates mature technologies in the field of water quality analysis, making the analysis system more complete, the operation is simple and fast, and the detection results are stable and reliable.
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), total phosphorus, turbidity, suspended solids
3. Strong scalability in the later stage, support ammonia nitrogen, CODmn, total nitrogen, phosphoric acid salt, total chromium, hexavalent chromium, copper, iron, nickel, zinc, nitrite and other parameters
4. Colorimetric integrated tube design, digestion and result reading share a reaction tube
5. Direct display of concentration results without conversion calculations
6. Multiple measurements and automatically remove outliers to improve accuracy
7. With the function of detecting abnormal prompts, such as blank comparison and overrange prompts
8. Built-in thermal printer and 5-inch high-definition color LCD screen
9. Data storage capacity up to 30,000 records, support 96 scalable Linear dispersion
10. Batch capacity up to 16/25 water samples/batch
Principle
The instrument uses a digestion Colorimetric integrated tube for operation, and the digestion and result reading of the sample share a reaction tube without liquid transfer. Absorbance measurement of the sample with a specific wavelength cold light source is used, and the system directly converts it into concentration value 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 external factors. At the same time, it has the function of detecting abnormal prompts to ensure the Reliability of results.
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、GB11893-89
Steps
1. Sample Handling Using Digestion Colorimetric Tubes
2. Put the reaction tube into the instrument for measurement
3. The instrument automatically makes multiple measurements and calculates the average
4. Read concentration results directly
5. Optional printing test report
Notice
• The instrument should be used under the condition of environment temperature 5~ 40 ℃ and humidity ≤ 85% without condensation
• Powered by AC 220V +/- 10% power supply
• Pay attention to COD digestion temperature and time requirements
• Stability of Optical inspection system
• Avoid using scratched or defective glass tubes
• Pay attention to the detection range and avoid over-range operation
