Which instrument is commonly used to measure ORP in wastewater?

The instrument commonly used to measure ORP, or oxidation-reduction potential, in wastewater is the ORP sensor. This device specifically detects the voltage in a solution that indicates its oxidizing or reducing capacity, which is crucial for evaluating the chemical processes occurring in wastewater treatment. The measurement of ORP provides important information about the water quality and can influence the treatment processes, such as the addition of chemicals to remove contaminants.

Other instruments like a pH meter focus on measuring acidity or alkalinity and do not directly provide ORP values. Similarly, conductivity meters measure the ionic content of a solution and assess its ability to conduct electricity, while flow meters monitor the rate of flow of fluids, neither of which can directly provide ORP measurements. Therefore, the ORP sensor is the precise tool needed for this specific analysis in wastewater applications.
