Overview
TR 6900NHN desktop STIP-scan is a TONGAO brand product, which can quickly determine the value of ammonia nitrogen and total nitrogen 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 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. Standard test parameters include ammonia nitrogen L, ammonia nitrogen H, total nitrogen L, total nitrogen H, late scalable COD, total phosphorus, phosphoric acid salt, turbidity, suspended solids, total chromium, hexavalent chromium, copper, iron, nickel, zinc, nitrite, CODmn and other parameters
2. Adopt digestion Colorimetric integrated tube, digestion and Colorimetric share a reaction tube, no need to transfer liquid
3. Direct display of concentration results, Absorbance measurement by specific wavelength cold light source, direct conversion by system algorithm
4. Multiple measurements and removal of abnormal values, 10 or more measurements of water samples, and the average value after removal of abnormal values
5. Detect abnormal prompt function, including blank comparison prompt, result excess range upper limit prompt
6. Built-in thermal printer, 5-inch high-definition color LCD screen
7. Large data storage capacity, can store 30,000 records, including project, date, time, sample ID, etc
8. Strong batch processing capability, each batch can handle 16/25 water samples
9. The operation interface supports membrane button operation, and the Chinese/English interface is optional
Principle
The instrument uses a digestion Colorimetric integrated tube for operation, and the digestion and result reading of the sample share a reaction tube, eliminating the need to transfer the liquid to the Colorimetric dish for detection. Absorption measurement is performed 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. Water samples are measured 10 times or more, and the average value is taken after removing the abnormal value to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the 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
All parameters are tested in accordance with national standards, industry standards or international standards
Steps
1. Sample Handling Using Digestion Colorimetric Tubes
2. Put the reaction tube into the instrument for measurement
3. The instrument automatically performs multiple measurements and calculates the average
4. Direct reading concentration result display
5. Optional to print test results
Notice
● The operating environment temperature of the instrument is 5~ 40 ° C, and the humidity is ≤ 85% without condensation
● Power supply mode is AC (220V +/- 10%), 50Hz
● Ammonia nitrogen test does not need to be digested, and total nitrogen test needs to be digested at 125 ℃ environment for 30 minutes
● Pay attention to the cleaning of Colorimetric tubes to avoid dirt, scratches and fingerprints affecting the test results
When a blank comparison prompt or over-range prompt appears, the sample needs to be checked or re-tested.
