Description

Technical Field

[0001] This utility model belongs to the field of laboratory instrument technology, specifically relating to a constant temperature immersion metal washing machine. Background Technology

[0002] The constant temperature immersion metal washing machine is used in the technical field of testing the cleaning power of metal cleaning agents, kitchen oil stain detergents, wood floor cleaners, and the determination and measurement of oil stains on metal materials and parts. It can also be used to evaluate and determine the cleaning power of detergents formulated with other surfactants and additives.

[0003] Existing constant-temperature immersion metal washing machines require manual placement of the test metal sheet, and the constant-temperature water bath required for the experiment cannot be well integrated with the washing machine. The required immersion time also needs to be manually measured, which inevitably affects the accuracy of the test. The washing switch of the metal washing machine also needs to be manually turned on. The entire experiment requires a lot of time from the experimenter. The current control method of the instrument can only be achieved through instrument display and control, and manual setting of operations and manual recording of data are still required. As a result, the experiment is prone to distortion, omissions, and human error. Since the experimental data cannot be traced, it is impossible to find the experimental data later, and the accuracy and completeness of the experiment cannot be guaranteed. Moreover, the interval between each operation cannot be standardized. Utility Model Content
