pH sensor

S1002  
Range: 0~14   
Accuracy: ±0.2
Resolution: 0.01     

The pH electrode composes of an internal reference electrode and an 
glass electrode. It is mainly used to measure the hydrogen ion concen-
tration of a solution and show the pH value of the solution.

Component

Usage

Connect the pH sensor into any port of the SensorDisc

Tighten the port of electrode probe and sensor

Unscrew the protective bottle of electrode probe

The electrode probe of pH sensor immersed in the solution completely 

Calibration

Calibrate before use，before Calibration, prepare two kinds of buffer solution with 

known pH value，e.g. pH4.00 andf pH9.18. The calibration process, please refer 

to“Notes”
