ORP Kit

The ORP Kit provides everything you need to measure oxidation reduction potential (ORP) in liquid solutions. ORP indicates how strongly a solution can act as an oxidising or reducing agent, and is commonly used in water quality monitoring, aquaculture, and hydroponics.

The kit includes a platinum rod ORP probe, an Atlas Scientific EZO ORP circuit board, calibration and storage solutions, and a BNC connector. The EZO circuit supports both UART and I2C communication, outputs readings from -1019.9 mV to +1019.9 mV with 0.1 mV resolution, and operates on 3.3V–5V for direct connection to Arduino, Raspberry Pi, and other microcontrollers.
