Operation process of selling sulfur dioxide analyzer

Application of sulfur dioxide residue analyzer:

Can be used for the determination of residual sulfur dioxide in food according to GB 5009.34-2022 national food safety standard, in compliance with the national standard method, acid-base titration method.

Characteristics of sulfur dioxide residue analyzer:

1. Intelligent microcomputer operation, microcomputer 7-inch color touch screen, display screen fixed in front of the machine, convenient for experimental personnel to operate, friendly and convenient interface, easy for experimental personnel to operate, and can independently set various instrument parameters;

2. Adopting far-infrared radiation heating, it can be switched on and off with a single channel or one button. Temperature dynamic display, heating temperature range: room temperature -650 ℃. Intelligent PID temperature regulation, temperature control accuracy can reach ± 1 ℃.

3. Four/six distillation units, capable of single hole control, can be switched freely during the micro boiling and full boiling experiments, and the micro boiling temperature and full boiling temperature can be set separately.

4. Time countdown. Real time display of remaining time, with an alarm indicating the end of distillation and automatic stop of heating and nitrogen blowing when the set time is reached.

5. The instrument is equipped with 4/6 magnetic stirring channels, which can be individually controlled for speed. Each magnetic stirring channel has an independent switch and can be infinitely adjusted for speed, with a stirring speed of 0-1400r/min.

6. Four/six nitrogen blowing units, controlled by independent rotor flow meters, with a flow range of 0-500ml/min (0-2L/min), and automatic pressure relief for overpressure.

7. After the distillation is completed and the instrument automatically stops heating, the anti backflow function is automatically turned on to prevent the absorption liquid from backflow during the cooling process of the flask, which may cause experimental failure.

8. The instrument can be cooled by external tap water, which can automatically start and automatically shut down after a delay, achieving water conservation. Optional high-power cooling water machine.

9. The instrument is equipped with an independent titration butterfly clip, and the fixing rod can be flexibly inserted and removed for easy titration.

10. The body adopts sheet metal spray coating, which is resistant to acid, alkali and organic solvent corrosion. Greatly improve the lifespan of experimental instruments.

11. The instrument uses a wide range of 24V safe voltage internally to ensure the personal safety of experimental personnel.

12. Temperature parameters can be calibrated to improve experimental accuracy.
