Oxidation-Reduction Potential (ORP) or redox sensors measure the ability of a solution to act as an oxidizing or reducing agent. The ionic potential information an ORP probe obtains is critical for various industrial applications, such as checking drinking water purity, monitoring the anaerobic activity of wastewater, and ensuring consistency in food production processes, such as baking. METTLER TOLEDO manufactures a versatile portfolio of high-quality ORP electrodes for lab and field applications. ORP sensors with silver, platinum, or gold rings offer the possibility to measure redox potentials in media with various chemical properties.

Origin of Precision

A combination ORP electrode with platinum ring indicator and S7 screw head.

Features

ARGENTHALTM - For a long electrode life

Thanks to the ARGENTHALTM reference system's silver-ion-free electrolyte, there is no danger of the junction becoming blocked by sulfides or proteins.

Flexible connectivity

The S7 sensor head offers flexibility and can easily be connected to any meter.

Spill free wetting cap

Easy-to-use wetting cap with a self-tightening screw lock that guarantees clean and secure electrode storage.
