Measure redox potential in microenvironments
With the tip size down to 10 µm, less than 5 seconds in response time, and 1 mV in resolution, the Unisense Redox microsensor offers a high quality research tool for reliable and fast measurements.
The microsensor construction makes it possible to use the Redox microsensor in a broad variety of research fields where non-destructive, fast and accurate measurements are required. The redox microelectrode is designed for research applications within:
- Environmental sciences
- Biomedical sciences
The Redox electrode tip will develop an electrical potential relative to the reference electrode when both electrodes are immersed in the same solution and connected to a high-impedance millivolt-meter e.g. the Unisense pH/mV-Meter. This potential reflects the tendency of the solution to release or take up electrons; also called the Oxidation-Reduction Potential (ORP). The Unisense Redox microelectrode can be used for measurements in salinities from 0 to full ocean strength.
The reference electrode can be either external (separate electrode) or internal; however, we only recommend internal references in applications where it is not possible to place two electrodes in the sample.
