Product description: Gravity - Analog ORP Sensor Meter Pro - Analog ORP Water Quality Sensor - DFRobot SEN0464
The Pro version of the Analog ORP Water Quality Sensor Meter features a platinum indicator electrode and a silver chloride reference electrode, which provides 24-hour ORP measurement and significantly increases product life. A new signal converter provides a more stable reference voltage, making the sensor measurement more accurate. The module is equipped with a screw connector and a waterproof connector to create an ORP monitoring system. The ORP sensor is used to test the purity of water (Oxidiation-Reduction Potential). ORP is a measure of the ability of an aqueous solution to oxidize and reduce, indicating the relative degree of oxidation or reduction. The unit of measurement is mV. If the oxidation-reduction potential is high, chemical oxidation is strong, whereas if the potential is lower, oxidation is weaker. A positive potential means that the solution shows some degree of oxidation, while a negative potential means that the solution shows some degree of reduction. ORP is an important indicator of water quality, but as a sensor alone cannot demonstrate water quality, it can be combined with other water quality indicators to better reflect the measurement.
