Overview
TONGAO TR 6900C desktop STIP-scan can quickly determine COD, ammonia nitrogen, total phosphorus, turbidity, suspended solids and other parameters in water, integrating mature technologies in the field of water quality analysis, making the entire analysis system more perfect, 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 other fields.
Features
1. Built-in two COD detection methods: the first method conforms to the HJ/T399-2007 national standard, and the second method is the import detection method.
2. Standard test parameters include COD (pre), COD (powder package), ammonia nitrogen, total phosphorus, turbidity, suspended solids.
3. Strong scalability in the later stage, support parameters such as total nitrogen, phosphoric acid salt, total chromium, hexavalent chromium, copper, iron, nickel, zinc, nitrite, CODmn, etc.
4. Colorimetric digestion tube is used, and a reaction tube is used for digestion and result reading without transferring liquid.
5. Direct display results, Absorbance measurement by a specific wavelength cold light source, the system algorithm directly converts the concentration value.
6. Multiple measurements and removal of abnormal values, carry out 10 or more measurements, remove abnormal values and take the average value to reduce interference.
7. Detect abnormal prompts, including blank comparison prompts, results exceeding the upper limit of the range, etc.
8. Built-in thermal printer and 5-inch high-definition color LCD screen, easy to operate.
9. Large data storage capacity, can store 30,000 records, including project, date, time, sample ID, etc.
10. High batch processing capacity, each batch can handle 16 or 25 water samples.
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
HJ/T399-2007、HJ535-2009、GB11893-89
Steps
1. Sample Handling is performed using a digestion Colorimetric integrated tube, and digestion and Colorimetric are completed in the same tube.
2. Put the processed sample into the instrument and use a specific wavelength cold light source for Absorbance measurement.
3. The instrument automatically performs 10 or more measurements, and takes the average value after excluding the abnormal value.
4. The system algorithm directly calculates and displays the sample concentration results.
5. If there is any abnormality, the instrument will prompt information such as blank comparison or over-range.
Notice
• During operation, pay attention to the environment humidity not exceeding 85% without condensation, and the environment temperature is between 5 and 40 ° C.
• When using the Colorimetric tube, avoid dirt, scratches, fingerprints or defects affecting the measurement results.
• The power supply of the instrument is AC 220V +/- 10%, 50Hz to ensure stable power supply.
• If there is an abnormal prompt during the detection process, check the sample or instrument status in time.
• Maintain instruments regularly to ensure Optical inspection Stability （≤ +/- 0.001A/20min) and Measurement accuracy.
