Oxidation Reduction Potential Sensor
Sensor specifications Sensor type: Combination electrode Electric Potential: 245~270mV Reference impedance: 10kΩ Stability: ±8mV/24h
Like the pH sensor, the ORP probe is a combination electrode whose output voltage is equivalent to the potential of the solution, so it will share the connection sockets with that sensor. The output of the circuitry to which it is connected is directly read from the analog-to-digital converter of the Smart Water sensor board, being the 2.048V reference subtracted to obtain the actual oxidation-reduction potential in volts (in this case, since this parameter is directly a voltage it is not necessary to call a conversion function). This sensor should be calibrated with the calibration solution for more accurate measurements.
