Introduction
The instrument can quickly determine the total chromium value in water, and integrates mature technologies in the field of water quality analysis, which makes the entire analysis system more complete, the operation is simpler and faster, and the detection results are more stable and reliable. Widely used in emergency monitoring, industrial wastewater, domestic (CN) sewage, sewage treatment, pharmaceutical and chemical industry, food, beverage, textile printing and dyeing, electroplating, papermaking, petroleum metallurgy, river management, scientific research units, colleges and universities and other fields.
Principle
1. Digestion colorimetric integrated tube
The digestion and colorimetric integrated tube is used for operation, and the digestion of the sample and the reading of the result share a reaction tube, and there is no need to transfer the liquid to the cuvette for detection.
2. Display the result directly
A cold light source with a specific wavelength is used to measure the absorbance of the sample, and the instrument system converts the detection result directly into the sample concentration value through a specific algorithm.
3. Measure multiple times and remove outliers
Measure the water sample 10 times or more, and take the average value after removing outliers, so as to reduce the influence of dirt, scratches, fingerprints or defective glass tubes on the results.
4. Detection of abnormal prompts
Prompts for abnormal detection, such as prompts for blank comparison, prompts for results exceeding the upper limit of the range, etc.
