Frequently Asked Questions

Q: Is this pH electrode sensor probe compatible with all Arduino boards?

A: Yes. The sensor uses a standard BNC connector for the pH probe and an XH2.54 3-pin interface that connects directly to Arduino's analog input pins. It is compatible with most popular Arduino boards including Uno, Mega, and Nano, making it a versatile choice for a wide range of DIY and professional pH measurement projects.

Q: How often should I calibrate the pH electrode sensor probe?

A: We recommend calibrating the sensor with standard calibration fluid at least once every six months under normal conditions. If the solution being tested contains many impurities or contaminants, you should calibrate more frequently to maintain measurement accuracy of ±0.1 pH.

Q: Can this sensor be used for pool water and aquarium monitoring as well as laboratory use?

A: Absolutely. With a full 0–14 pH measuring range and an operating temperature of 0–60°C, this sensor is suitable for a variety of applications including swimming pool water testing, aquarium monitoring, hydroponics, and laboratory experiments. Its durable composite electrode design ensures reliable readings across these different environments.

Q: Does the package include calibration fluid or an Arduino controller?

A: The package includes one pH electrode sensor probe and an instruction manual. Calibration fluid and Arduino controllers are not included and must be purchased separately.
