Gravity Analog Industrial ORP Sensor Pro Meter

This set from DFRobot measures the oxidation-reduction potential (ORP) of water in the range of -2000 to +2000 mV. The industrial probe with platinum measuring electrode and silver-silver chloride reference electrode is designed for round-the-clock monitoring. The Gravity signal converter has a stable voltage reference so that fluctuations of the supply do not falsify the measurement. It outputs an analog voltage that an Arduino, for example, reads in.

A high potential indicates strongly oxidising, a low potential reducing conditions. ORP is used together with other values to assess water quality. The set is the improved version of the Gravity Analog ORP Sensor for Arduino.
