Description

As an upgraded version of this new generation, the Industrial Grade Analog ORP Sensor Meter PRO ORP probe employs a platinum indicator electrode and silver-silver chloride reference electrode, which makes it available for 24-hour online ORP monitoring and greatly enhances 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 an ORP monitoring system.

ORP(Oxidation-Reduction Potential) 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.
