Analog, pH Sensor Meter Kit for Arduino - High Accuracy pH Measurement for Water Quality Testing, 3.3-5.5V

The Analog pH Meter is designed for use with Arduino controllers, providing a practical and convenient “Gravity” connector interface. It measures pH in the range of 0–14 with an accuracy of ±0.1 pH at 25°C. The module features an LED power indicator, BNC connector, and PH2.0 sensor interface.

To use, simply connect the pH sensor via the BNC connector and plug the PH2.0 interface into any Arduino analog input port. The meter comes in a compact plastic box with foam inserts for safe storage and portability.

This pH meter is ideal for a variety of projects, such as building DIY pH meter gadgets or water monitoring stations for tanks. Note that this is a laboratory probe and should not be immersed in liquid for extended periods. The probe should be stored in KCl solution, not dry, and buffer solutions are not included. Minor white particles on the protective foam may appear due to KCl crystallization, which is normal.
