Gravity: Analog Industrial ORP Sensor Meter Pro for Arduino

This upgraded ORP Sensor Meter for Arduino features a highly durable platinum indicator electrode alongside a silver-silver chloride reference electrode, designed for continuous 24-hour online monitoring. The advanced signal converter in this model ensures more stable voltage references, eliminating disruptions from voltage fluctuations.

Included in the accessory packet are screws, copper columns, and waterproof connectors, making it easier to construct a reliable ORP monitoring system. The sensor accurately measures the Oxidation-Reduction Potential (ORP) of aqueous solutions, a key indicator of their oxidative or reductive strength.

Expressed in millivolts, ORP readings highlight the chemical activity of the solution. High ORP values indicate strong oxidative potential, whereas lower values suggest reduced oxidative capacity. Positive ORP values imply a tendency toward oxidation, while negative values suggest reductive properties, offering valuable insights into water quality and ecological conditions when used in conjunction with other measurements.
