Affordable and User-Friendly: Our pH electrode sensor probe is specifically designed for Arduino controllers, offering a cost-effective and straightforward solution for open-source pH measurement. With easy wiring and practical features, it caters to hobbyists and professionals alike. Convenient Connectivity: Featuring a BNC connector for the pH probe and an XH2.54 interface for seamless integration for Arduino controllers, this pH replacement probe ensures a hassle-free setup. Simply connect the pH sensor to the onboard BNC socket probe and the XH2.54 interface for Arduino's analog input for effortless pH monitoring. Reliable and Durable Design: The pH sensor utilizes a composite electrode combining a glass electrode and a reference electrode in a non-refillable plastic shell, offering accurate measurements of hydrogen ion activity in aqueous solutions-or, in other words, the pH value. This design ensures long-term reliability and precision. Protective Packaging: Each bnc socket probe comes in a sturdy black box, cushioned with black sponge padding. This not only provides optimal protection for the component during transit and storage but also adds an elegant touch to the product presentation. Comprehensive Support Materials: Included with every pH probe is a detailed instruction manual for the pH composite electrode, facilitating easy secondary development for users. Whether you're a seasoned developer or for Arduino projects, this guide will help you get started with your pH measurement tasks quickly and efficiently.
