SKD-320 sulfur dioxide detector Introduction
The principle of the sulfur dioxide detector SKD-320 distillation method: Distillation method, suitable for color wine and glucose syrup, fruit mash. The sulfur dioxide detector SKD-320 method is to acidify and thermally distill the sample in a closed vessel to release sulfur dioxide therein. The release is absorbed with a lead acetate solution. After absorption, it is acidified with concentrated hydrochloric acid and titrated with an iodine standard solution. The amount of sulfur dioxide in the sample is calculated based on the amount of iodine standard solution consumed. Features
1.Sulphur dioxide detector SKD-320 shell is made of the best ABS engineering plastics. It can resist strong acid and alkali and never rust!
2.Sulphur dioxide detector SKD-320 The internal connection of each pipeline is made of special hose with high temperature resistance and strong acid and alkali resistance, which improves the accuracy and life of the instrument. It does not need to be replaced in 3 years.
The sulfur dioxide detector SKD-320 instrument and hydrochloric acid use a suction pump to ensure the consistency of each time the hydrochloric acid is added, so that the distillation repeatability is improved.
3.Automatic compensation of the distillation cup heating time
4.Stop the distillation cup dry burning Technical Parameters
