Gravity Analog Industrial ORP Sensor Pro Meter

The Analog Industrial ORP Sensor measuring device Pro for Arduino is an improved version of the Gravity Analog ORP Sensor. It uses a platinum indicator electrode and a silver-silver chloride reference electrode, enabling a 24-hour online ORP monitoring, and improves the product's lifespan. The new signal converter ensures a stable reference voltage, so sensor readings are not affected by fluctuations in the supply voltage. ORP is a measure of the ability of an aqueous solution to oxidize and reduce, and the meter provides information about the degree of oxidation or reduction. It is an important index for detecting water quality and can be used in combination with other water quality indices to better assess the ecological environment.
