1, high precision intelligent pH controller, large screen LCD display real-time dynamic pH value and temperature value, beyond the scope of the alarm.

2, a variety of control measurement mode: automatic, manual, stop, can be freely converted to achieve a multi-purpose machine.

3, single pump with acid or alkali, suitable for use as a liquid (acid or alkali) to adjust the pH control.

4, the use of OLED high-definition LCD window, showing the current motor speed and the state of work, plus liquid speed can be stepless speed regulation.

5, pH value of the upper and lower limits of the free set, the set value and the measured value at the same time display.

6, pH electrode can be a single point or two point correction, pH value and temperature automatic measurement, pH value can be automatically adjusted according to temperature.

7, the stepper motor control of a peristaltic pump with liquid, liquid contact inlet pump, not in contact with the pump body, no pollution.

8, the matching of different forms of pH precision composite electrode, and the electrode sheath with PTFE material and extension rod in high temperature, reactor, reactor for controlling and adjusting the pH value of the implementation of special container.

9, control mode: automatic, manual, stop

A: automatic mode: the instrument will be based on real-time detection of the pH value and set value, automatically start / stop adding acid (plus alkali), adjust the pH value to the set range.

B: manual mode: not controlled by the pH controller, rotation, manual start / stop acid (plus alkali), adjust the pH value to the set range. Can also be used to quickly adjust, or to drive the bubble inside the tube, or for the delivery of other liquids

C: stop: stop adding liquid action, but the pH value in real time detection and display; for standby or adjustment at the end, can also be used as online pH value measurement display terminal.

This product has won the national invention patent, patent number: ZL 201420406055.8 ZL 201420406067 ZL 201410349779.8
