• Small in size, lightweight and easy to operate. Can be used as pH measurement as well as titration volumetric analysis.
• When doing pH measurement, the panel adopts potentiometer and band switch to control and switch; when doing titration analysis, it adopts highly reliable touch control, so that users can easily choose between automatic titration and manual titration.
• Built-in precision automatic polarity reversal circuit, and automatically track the terminal potential, the operator does not need to toggle any control switch, which is convenient to use and improves the control accuracy.
