Overview
The TR 6900Cr desktop STIP-scan is a TONGAO brand product that can quickly determine the total chromium value in water. The instrument integrates mature technology in the field of water quality analysis, making the entire analysis system more complete, the operation is simpler and faster, and the detection results are more stable and reliable.
Features
1. Adopt digestion Colorimetric integrated tube design, digestion and Colorimetric are completed in the same reaction tube
2. Direct display of test results, the system automatically converts Absorbance to concentration value
3. Support multiple measurements and automatically remove abnormal values to improve detection accuracy
4. With the function of detecting abnormal prompts, including blank comparison prompts and overrange prompts
5. Large capacity data storage, can store 30,000 detection records
6. Built-in thermal printer for convenient output of results
7. Support batch processing, each batch can handle 16-25 water samples
8. Equipped with a 5-inch high-definition color LCD screen
9. Supports multiple communication interfaces, including USB and LAN
Principle
Absorption measurement is carried out using a specific wavelength cold light source, and the system converts the test result directly into the sample concentration value through a specific algorithm. 10 or more measurements are made on the water sample, 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
