  • The automatic sample introduction system can place 40 digestion tubes at the same time to meet the requirements of batch automatic analysis.

  • The sample storage adopts a rectangular structure design. After the sample is digested, it can be put directly on the machine together with the digestion tube rack, which is convenient and fast. Compared with disk-type sample storage, the cumbersome operation of secondary transfer of the digestion tube is reduced.

  • The system automatically shuts down after 60 minutes of unattended operation, which is energy-saving, safe and reliable.

  • The instrument has a built-in protein coefficient query table for users to read, query and participate in system calculations. When the coefficient = 1, the analysis result is "nitrogen content". When the coefficient > 1, the analysis result is automatically converted to "protein content" and displayed and stored. ,Print

  • The R, G, and B three-color light intensity automatic adjustment system can adapt to the analysis of different formulas of boric acid absorption solutions and samples of different concentrations.

  • The internal standard of titrant concentration eliminates system errors and is highly precise and convenient.

  • Automatic cleaning of alkali pipeline to prevent pipeline blockage and ensure liquid supply accuracy.

  • The standard configuration refrigeration system can save a lot of water resources for users, and is energy-saving and environmentally friendly.

  • The unique "sample weighing data automatic upload data package" eliminates the need to record and enter the weight of samples one by one, reducing input errors and improving work efficiency.
