Overview
TR 6900NH desktop STIP-scan is a TONGAO brand product, which can quickly detect ammonia nitrogen value in water. It integrates mature technology in the field of water quality analysis to make the analysis system more complete, 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.
Features
1. Colorimetric digestion tube, no need to transfer liquid, easy to operate.
2. Direct display of concentration results, through specific wavelength cold light source and algorithm conversion Absorbance.
3. Multiple measurements and removal of abnormal values to reduce the influence of external factors.
4. Detect abnormal prompt function, including blank comparison and overrange prompt.
5. High Accuracy measurement, error ≤ +/- 5%, Repeatability ≤ +/- 5%.
6. Large amount of data storage, can store 30,000 records.
7. Built-in thermal printer, easy to print results.
8. It has strong scalability in the later stage and supports various parameters such as total phosphorus, total nitrogen, and suspended solids.
Principle
The instrument adopts a digestion Colorimetric integrated tube, and the digestion and result reading of the sample share a reaction tube without transferring the liquid. Absorbance measurement of the sample using a specific wavelength cold light source, 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 dirt, scratches, etc., and prompt the detection of abnormalities.
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
Ammonia nitrogen detection method conforms to HJ535-2009 "Water quality, determination of ammonia nitrogen, Nessler reagent Spectrophotometric method, spec-trophotometry"
Steps
1. Sample manipulation using digestion Colorimetric tube.
2. Absorbance measurement and direct display of concentration results.
3. The system makes multiple measurements and removes outliers.
4. Prompt the user when an abnormality is detected.
Notice
- Make sure to use the Digestion Colorimetric tube to avoid liquid transfer.
- Pay attention to environmental conditions, temperature 5~ 40 ℃, humidity ≤ 85% no condensation.
- Avoid dirt, scratches or fingerprints affecting measurement results.
Power supply using AC (220V +/- 10%), 50Hz.
- Pay attention to abnormal prompts during operation, such as blank contrast or overrange.
