[0002] Sulfur dioxide has bleaching, anti-corrosion and antioxidant effects. Fumigating Chinese medicinal materials and decoction pieces with sulfur can make the products bright in color and prevent them from becoming moldy and deteriorating. At present, sulfur dioxide analyzers are commonly used in the inspection and testing of food and medicine. The method is generally to set up a system of scattered equipment such as a heated water bath, iron stand, glass condenser tube, and chiller.

[0003] Currently, measuring instruments are frequently used in laboratories for testing. During laboratory use, the inventor discovered a series of problems with existing measuring instruments.

The guide tube entering the sample bottle is usually in an inclined state, which is not conducive to the flow of sulfur dioxide. Furthermore, existing measuring instruments mostly have a single fixed height for the condenser tube. When using condenser tubes of different lengths, the single fixed height cannot be adjusted according to the length of the condenser tube, resulting in poor fixation effect. Utility Model Content
