Full Description Specification

The standard solutions are perfect for immersing the electrode and establishing initial readings which should fall within the 200 to 275 mV range at 25°C/77° F, for example, or within the parameters you are testing.

If the reading is outside the indicated range, clean and condition the ORP Electrode in Hanna pre-treatment solution. Use HI-7092 for oxidising or HI-7091 for reducing pre-treatment.

HI-7091L Pre-treatment Reducing Solution for ORP electrodes (500 mL)

HI-7091L is a reducing pre-treatment solution for the conditioning of an ORP electrode which is used to measure reduction reactions.

ORP (Oxidation Reduction Potential) electrodes are used to measure a chemical reaction in which one species is being oxidised and another is being reduced. The loss of electrons by an element or compound is known as oxidation reaction, while the gaining of electrons by an element or compound is known as reduction reaction.

Using the HI-7091L reducing pre-treatment solution before taking a measurement provides for a faster response time in a reducing environment.

Soak the ORP electrode in the pre-treatment solution for 15 minutes before use.
