ORP sensor

The ORP sensor ML72m measures the ability of a solution to act as an oxidizing or reducing agent. ORP stands for oxidation-reduction potential, also known as Redox Potential. The ORP sensor consists of an ORP electrode and an amplifier. The ORP electrode has been built into a long plastic tube with an opening at the bottom side and is supplied with a storage bottle containing a protective solution.

Suggested experiments:
Redox reactions control the behavior of many chemical constituents in drinking water, wastewater and aquatic environments. The reactivity and solubility of critical elements in living systems are strongly dependent on redox conditions. ORP values are used much like pH values to determine water quality. For example for swimming pools at a normal pH value between 7.2 and 7.6, the ORP value must be kept above 700 mV to kill unwanted organisms. In contrast, in order to support life, natural waters need a much lower ORP value. Generally ORP values above 400 mV are harmful to aquatic life.
The ORP sensor can also be used for redox titrations to determine the equivalence point in an oxidation-reduction reaction.

The ORP sensor ML72m is a digital sensor (on-sensor digital conversion), which gives calibrated values of the measured quantity. This sensor can only be connected to the CMA MoLab interface and not to other CMA interfaces such as VinciLab, CoachLab II+ or EuroLab.

Technical specifications of the sensor are described in its User's guide.
