DFRobot Gravity Analog ORP Sensor Meter PRO

Description Gravity Analog ORP Sensor Meter PRO by DFRobot Offers 24-hour online ORP monitoring Comes with an Industrial ORP Probe Measures the ability of oxidation and reduction Features an important index of water quality detection Can be combined with other water quality indexes The DFRobot Gravity Analog ORP Sensor Meter PRO is a measure of the ability of oxidation and reduction of an aqueous solution, which is the relative degree of oxidizing or reduction. The unit is mV. If the oxidation-reduction potential is high then chemical oxidation is strong, while if the potential is lower then oxidation is weaker. The positive potential means that solution shows a certain degree of oxidation, while the negative potential means that solution shows a certain degree of reduction. ORP is an important index of water quality detection, although it can not separate water quality independently, it can be combined with other water quality indexes to reflect the ecological environment better.
