You will find everything you need in the SEN-10972 pH Sensor Kit

This kit contains everything you need to perform the most accurate possible pH measurements and then save them for later analysis on an Arduino board. The kit offers you 3 buffer solutions for calibrating different pH levels, a storage solution, a pH probe, and a dedicated electronic circuit for pH measurement on Arduino, Raspberry Pi, or PIC. Connecting up your probe to the pH circuit couldn’t be simpler: you just have to calibrate the BNC connector then use this to plug the pH probe into its circuit.

Accurate measurements with the SEN-10972 pH kit

Your pH Sensor Kit is capable of detecting and measuring pH values between 0 and 14, returning 95% of results within a calculation time of 1 second, and with an adjustment window of ±0.2 pH.
