7. Built-in thermal printer and 5-inch high-definition color LCD screen.
8. Large data storage capacity, can store 30,000 records.
9. High batch processing capacity, supporting 16/25 water samples/batch.
10. Optical inspection Stability High ，≤ +/- 0.001A/20min, light source life 100,000 hours.
Principle
The instrument uses a digestion Colorimetric integrated tube for operation. The digestion and result reading of the sample share a reaction tube, so there is no need to transfer the liquid to the Colorimetric dish for detection. Absorption measurement is carried out on the sample with 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. Perform 10 or more measurements on the water sample, and take the average value after removing the abnormal value to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the results. At the same time, it has the function of detecting abnormal prompts, such as blank comparison prompts, results exceeding the upper limit of the range prompt, etc.
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 with Digestion Colorimetric Tubes.
2. Put the sample into the instrument for measurement.
3. The instrument automatically performs multiple measurements and calculates the average.
4. Directly read and display the test results.
Notice
• When using the Digestion Colorimetric integrated tube, ensure that the tube body is clean and free of scratches.
• Pay attention to detecting abnormal cues, such as blank contrast or overrange conditions.
• Operating environment temperature should be maintained at 5~ 40 ℃, humidity ≤ 85% without condensation.
• Power supply mode is AC (220V +/- 10%), 50Hz to ensure stable power supply.
• Stability of Optical inspection system.
• Pay attention to the accuracy of information such as sample ID when storing data.
