The DNM-200 automatic dosing machine is a product of our company that incorporates the advantages of similar domestic and international products, integrating modern high-tech techniques, and effectively addressing some of the drawbacks of previous similar products. (1) The control system utilizes imported integrated circuit microcomputer control, allowing the operator to input relevant parameters via the keyboard; (2) An additional display system, namely CRT (cathode ray tube) display, has been added; (3) The printing system can be set to print at regular intervals or at any time, with the content being customizable; (4) The execution system employs a specially designed valve body similar to a ‘three-way’, with the medicine inlet and outlet pipes being directly connected and having a larger diameter, ensuring smooth operation even with impurities in the medicinal liquid as abundant as in a slurry, preventing blockages, and allowing the execution system to be used for long periods without failure. Additionally, the配备药液恒位箱 increases the accuracy of dosing.
