·Product Overview

※ 1. 7.5-inch large screen true color touch screen display, Chinese human-machine interface, simple and easy to understand operation process；

※ 2. Import control platform, imported pipelines, and instruments are reliable and accurate；

※ 3. With a large data storage capacity, data within three years can be freely queried and printed;

※ 4. Imported self-priming diaphragm pump is used for liquid supply, which can effectively save laboratory space；

In standby mode, the temperature of the steam cylinder is always maintained at 80 ℃, which can quickly generate steam and shorten waiting time;

※ 6. Real time display of titration curve. Real time observation and analysis of titration process；

When steam is generated, the cooling water will automatically turn on. When no steam is generated, the cooling water will automatically turn off, maximizing the savings of cooling water and avoiding unnecessary losses caused by operators forgetting to turn off the water source due to negligence；

※ 8. Built in automatic cleaning titration cup program can prevent the influence of non neutral residual liquid in the titration cup on low content and blank samples, improving system accuracy and reliability;

Before adding alkali, an appropriate amount of distilled water is automatically added to dilute the strong acid sample, and the sample can also be heated appropriately to prevent strong reactions of acid and alkali；

※ 10. Automatic intermittent alkali addition process can reduce excessive acid and alkali reactions；

※ 11. When not placed in the digestion tube, the system does not work. When the safety door is not pulled down, the system does not heat up to ensure safe operation；

※ 12. Equipped with steam system over temperature and over pressure protection functions to prevent danger caused by high steam system pressure;

※ 13. Equipped with automatic water replenishment function for steam cylinder to prevent dry burning due to water shortage;
