Overview
TR 6900P desktop STIP-scan is a professional equipment launched by TONGAO, which can quickly determine the total phosphorus value in water, integrate mature technology in the field of water quality analysis, so that the analysis system is perfect, the operation is simple and fast, 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 universities and other fields.
Features
1. Colorimetric digestion tube is used, sample digestion and result reading share a reaction tube, no need to transfer liquid.
2. Direct display results, Absorbance measurement by a specific wavelength cold light source, the system algorithm directly converts the concentration value.
3. Multiple measurements and removal of abnormal values, 10 or more measurements of water samples, after removing abnormal values, the average value is taken to reduce the influence of external factors.
4. Detect abnormal prompts, including blank comparison prompts and result overrange upper limit prompts.
5. Built-in thermal printer and 5-inch high-definition color LCD screen, easy to operate.
6. Large data storage capacity, can store 30,000 records, support 96 Linear dispersion expansion.
7. Strong batch processing capability, each batch can handle 16 or 25 water samples.
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 carried out on the sample through 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, remove the abnormal value and take the average value to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the results, 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
GB 11893-89 "Water Quality, Determination of Total Phosphorus, Ammonium Molybdate Spectrophotometric method, spec-trophotometry"
Steps
1. Sample Handling with Digestion Colorimetric Tubes.
2. Place the sample in the instrument and initiate the measurement procedure.
3. Absorption measurements are automatically performed 10 times or more.
4. The system calculates the average value after excluding outliers.
5. Direct reading and display of total phosphorus concentration results.
6. Optional printing or storage of inspection data.
Notice
• Make sure to use a digestion Colorimetric tube to avoid liquid transfer errors.
• Pay attention to sample compatibility, support 16mm and 25mm round tubes.
• The operating environment humidity should be ≤ 85% without condensation, and the temperature should be within the range of 5~ 40 ° C.
• Power supply mode is AC (220V +/- 10%), 50Hz to avoid voltage instability.
• Stability of Optical inspection system is checked regularly to ensure Measurement accuracy.
• Pay attention to abnormal prompts, such as blank comparison or overrange, and deal with them in time.
• Ensure that information such as sample ID is complete when storing data.
