◆ High precision intelligent pH controller, with a large LCD screen displaying dynamic pH and temperature values in real-time, and an alarm for exceeding the range.

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

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

◆ Adopting OLED high-definition LCD window, it displays the current motor speed and working status separately, and the liquid addition rate can be infinitely adjusted.

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

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.

◆ Adopting 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.

◆ 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.

◆ Optional laboratory intelligent control module system, realizing remote intelligent information management of the Internet of Things. The cloud platform can monitor the operation status of this instrument in real time, including user information, usage time, test duration, usage frequency, different usage scenarios, and other data.
