Technical features of the product:
Adopting microprocessor technology and LCD display technology, the operation is simple, easy to master, and tends towards humanization;
Intelligent calibration interface ensures accurate temperature and pH measurement;
The pH value has automatic temperature compensation;
The peristaltic pump is driven by a stepper motor, which is easy to accurately control the speed of liquid addition and is very suitable for precise control of pH value;
Memory function: Various parameters set before shutdown can be stored in the EEPROM inside the machine. At the next startup, the working state before shutdown can save the trouble of setting up each time;
● Pollution free: As the liquid only comes into contact with the hose, the driver, pump head, and fluid are not contaminated;
● Selection of multiple pump heads and multiple dosages: This system can use various pump heads designed and produced by Chenghe, with different hose diameters and adjustable driver speeds to suit different dosages per unit time. At the same time, all types of pump heads can supply liquid with minimal shaking and no dripping;
Adopting ABS engineering plastic shell, the appearance is exquisite, beautiful, and meets hygiene requirements.
This machine is equipped with a standard communication interface (RS485), which can be connected to upper control devices such as computers to automatically store and save data on pH change curves, temperature change curves, and pump body speed curves during the control process. The upper computer can load our company's automatic storage software.
