electrode. When the electrode is immersed in the solution to be tested, the difference between the stable
potential of the reference electrode and the potential generated by the glass sphere is proportional to the
H+ concentration in the solution.
The pH sensor measures data with stability, reliable performance and easy installation. The appearance of
the pH sensor is shown in Figure 4.
Important Tip1: When using a new pH electrode, the electrode should be immersed in distilled
water for a period of time, usually 24 hours or more, in order to form a good hydration layer.
There should be no air bubbles between the bulbs of the inner electrodes of the glass electrodes, and
if there are bubbles, the bubbles can escape easily.
Important Tip 2: Provided the pH is used in high sulfur ion environments, which is easy damaged
and with short life time.

2.3 ORP Sensor
Principle:
ORP sensor is a composite electrode in which the indicator electrode and the reference electrode are
combined. Also known as REDOX electrode. The data is stable and reliable.
The appearance of the ORP sensor is shown in Figure 5.
IMPORTANT: When using the new ORP electrode, the electrode should be immersed in distilled
water for a period of time, usually more than 24 hours, in order to form a good hydration layer.
