The ZS02-3000A sulfur dioxide detector is a highly integrated device that integrates multiple functions such as heating, distillation, water circulation, and nitrogen blowing. It is designed specifically for the determination of sulfur dioxide residues in traditional Chinese medicine and herbal slices. The following is a detailed introduction to the device:

1. Function integration and principles

Following pharmacopoeia standards: According to the requirements of General Rule 2331 in Part IV of the pharmacopoeia, the sample is processed using distillation method. Specifically, the sulfite series substances in the sample are converted into sulfur dioxide after acid addition, and then enter the absorption bottle containing hydrogen peroxide with nitrogen gas flow, where they are oxidized into sulfate ions. Finally, the residual sulfur dioxide in medicinal materials or decoction pieces is determined and calculated by acid-base titration method.

Multi functional integrated design: It integrates functions such as heating, distillation, water circulation, and nitrogen blowing, and can provide processing capabilities for 3-5 samples (including blank and parallel samples) simultaneously. This not only improves the accuracy of detection data, but also greatly reduces working time.

2. Main components and characteristics of ZS02-3000A sulfur dioxide detector

heating module

Efficient and safe: The use of sealed infrared ceramic heating sleeves has good heat collection and efficient heating efficiency, while effectively preventing equipment damage caused by liquid leakage.

Flexible temperature control: Equipped with high, medium, and low heating rate control functions, and the heating device can independently control temperature. Users can adjust the heating power according to their needs.

Intelligent Reminder: Equipped with a heating countdown function, and automatically stops heating upon completion through a beep reminder.

Distillation module

Excellent Material: Made of high borosilicate material, it has excellent heat resistance and durability.

Cooling water circulation system

Efficient and energy-saving: The cooling system composed of built-in or external high-power fans and high-efficiency heat sinks ensures good condensation effect, and supports one click shutdown and one click water replenishment operation, making it convenient to use and energy-saving.

Nitrogen blowing module

Precise control: The host is equipped with a nitrogen main interface, and the nitrogen flow rate of each single hole can be individually controlled through a high-precision flow meter to ensure the stability and accuracy of the nitrogen blowing process. In addition, an external nitrogen generator or nitrogen cylinder can be used as the gas source.

3. Operation and display interface of ZS02-3000A sulfur dioxide detector

Full touch screen control: Using LCD touch screen as the human-computer interaction interface, making the operation simpler, more intuitive, and easier to control.
