[0002] A continuous stirred tank reactor, also known as a continuous stirred tank reactor, is a specialized piece of equipment used in chemical production to achieve continuous material flow and chemical reactions. Its core characteristic is that the material input, reaction, and product output are all uninterrupted continuous processes. Existing continuous stirred tank reactor technologies cannot address the shortcomings of pH meters not being able to be cleaned and calibrated during continuous reactor production, nor can pH probes be replaced without shutting down the reactor. Therefore, we propose an online pH meter cleaning and calibration device. Utility Model Content
