The Atlas Scientific EZO™ ORP Circuit is a compact, high-accuracy module designed to measure the Oxidation-Reduction Potential (ORP) of water and other liquids. It provides accurate readings for water quality monitoring, water treatment, chemical processing, and automated testing systems.
With an accuracy of ±1 mV and support for both UART and I2C communication, this module is easy to integrate into Arduino, Raspberry Pi, and other microcontroller projects.
Its small size, low power requirements, and single-point calibration make it ideal for both laboratory and industrial applications.
