This is an Electrode Probe for Liquid pH Value Detection, perfect for measuring water quality and other parameters without the need for an expensive pH meter. If you're finding it tricky to use with Arduino, this sensor module is the solution.
The probe features a pH glass electrode combined with a reference electrode, making it an effective sensor for measuring the pH (H-ion concentration) of aqueous solutions. It’s widely used in various applications for accurate pH detection.
The pH electrode has a single cylinder design, allowing direct connection to pH meters, controllers, or any device with a BNC input terminal. The probe provides accurate, reliable, and almost instantaneous pH readings.
