The Laboratory ORP (Oxidation - Reduction Potential) Sensor measures the tendency of a solution to either accept or donate electrons, indicating its oxidizing or reducing capacity. It consists of a platinum electrode that reacts with the redox species in the solution. A reference electrode provides a stable potential for comparison. This sensor is essential in electrochemistry research, for example, in studying corrosion processes. In the swimming pool industry, it helps control water treatment by monitoring the effectiveness of disinfectants like chlorine. The laboratory ORP sensor can quickly respond to changes in the redox state of a solution, offering real - time data. Its compact size and easy - to - use interface make it suitable for both bench - top and in - line applications. It also has a wide measurement range, accommodating various types of samples from highly oxidizing to reducing environments.
