Affordable and User-Friendly: Our pH electrode sensor probe is specifically designed for 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 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 's analog input for effortless pH monitoring. Reliable and 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 solutions-or, in other words, the pH value. This design ensures long-term reliability and . Protective Packaging: Each bnc socket probe comes in a sturdy black box, cushioned with high-quality black sponge padding. This not only provides optimal protection for the component during transit and storage but also adds an 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 or for new projects, this guide help you get started with your pH measurement tasks quickly and efficiently.
