1. High precision intelligent pH controller, large screen LCD real-time display of dynamic pH and temperature values, and alarm for exceeding the range.

2. Multiple control measurement modes: automatic, manual, stop, can be freely switched, achieving multiple uses for one machine.

3. Single pump for adding acid or alkali, suitable for using only one liquid (acid or alkali) to adjust and control the pH value.

4. Using OLED high-definition LCD window, the current motor speed and working status are displayed separately, and the liquid addition rate can be infinitely adjusted.

5. The upper and lower limits of pH value can be freely set, and the set value and measured value are displayed simultaneously.

6. The pH electrode can be calibrated at one or two points, and the pH value and temperature can be automatically measured. The pH value can be automatically calibrated according to temperature.

7. Using a stepper motor to control the peristaltic pump for liquid addition, the liquid contacts the inlet pump tube without touching the pump body, resulting in no pollution.

8. Choosing different forms of pH precision composite electrodes, as well as electrode sheaths and extension rods made of PTFE material, can be used to monitor and adjust pH values in special containers at high temperatures, reaction vessels, and reactors.

9. Control mode: automatic, manual, stop

A: Automatic mode: The instrument will automatically start/stop adding acid (alkali) and adjust the pH value to the set range based on the real-time detected pH value and the set value.

B: Manual mode: not controlled by the pH controller, continuously rotating, manually starting/stopping acid (alkali) addition, adjusting the pH value to the set range. It can also be used for quick adjustment, or to drive away bubbles inside the tube, or for the transportation of other liquids

C: Stop: Stop the liquid addition action, but the pH value is detected and displayed in real-time; Used for standby or adjustment purposes, it can also be used as an online pH measurement display terminal.

10. Optional laboratory intelligent control module system can be configured to achieve remote intelligent information management of the Internet of Things. The cloud platform can monitor the real-time operation status of this instrument, including user information, usage time, test duration, usage frequency, and different usage scenarios.
