{"title":"Gravity: Analog ORP Sensor Meter PRO","handle":"gravity-analog-orp-sensor-meter-pro","url":"/products/gravity-analog-orp-sensor-meter-pro","description":"As an upgraded version of Industrial Gravity: ORP Sensor Meter For Arduino, this new generation ORP probe employs platinum indicator electrode and silver-silver chloridereference electrode, which makes it available for 24-hour online ORP monitoring and greatlyenhances product durability. The new signal converter adds a more stable voltage reference so that the sensor readings would be no longer affected by supply voltage fluctuations. Besides, there are screws, copper columns and waterproof connectors included in the accessory packet to help you conveniently build up ORP monitoring system.  ORP(Oxidation-Reduction Potential) is a measure of the ability of oxidation and reduction of an aqueous solution,  which the relative degree of oxidizing or reducing. 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.
