## Description

IDUINO PH Sensor Analytical Surver Electrode PH Electrode E201-C BNC Analog For Arduino S28

## Features

- pH electrode probe has reliable reading accuracy and can provide almost instantaneous reading of pH value, thus it can be used in water purification processes. This pH sensor probe is refillable, which means its KCl (potassium chloride) salt solution can be refilled to extend the lifespan of the sensor, but user has to be careful not to spill the salt solution or otherwise the sensor will not work properly.
- The salt solution is used as a differentiator for the sensor to compare its pH level with the measured liquid in order to produce an accurate change in output which is readable by most controllers. Since the solution is refillable, you can always change the solution if it is contaminated. Replenishment must be made when the solution is less than 2cm in the tube of probe.
- The probe has BNC connector which can integrate with majority type of PH meter and controllers, suitable for application in aquarium, hydroponic, aquaponic, laboratory, etc.
