The Edu-Logger ORP (Oxidation Reduction Potential) sensor can be used to quantify whether a substance is a strong oxidizing agent or a strong reducing agent. For example, the ORP electrodes are used to measure the oxidizing ability of chlorine in swimming pools.
The electrode has two components: a measuring half-cell comprised of platinum metal immersed in the solution in which the redox reaction is taking place, and a reference half-cell (sealed gel-filled Ag/AgCl) to which the platinum half-cell is referenced.
As with all Edu-Logger Sensors this must be used with one of the Edulogger communication modules:
Graphic Display Module
( 900-246 )
· Used in the field of Chemistry.
· Attached electrode cased in a storage bottle or protective boot covering the electrode tip. The bottle or boot contains a foam or a cotton ball moist with distilled water.
· The sensor is pre-calibrated at the factory.
· Experiment duration: 1 second to 31 days.
