Product Specification

ENV-40-ORP ORP Probe Operating principle
ORP stands for oxidation/reduction potential. Oxidation is the loss of electrons and reduction is the gain of electrons. The output of the probe is represented in millivolts and can be positive or negative.

Just like a pH probe measures hydrogen ion activity in a liquid; an ORP probe measures electron activity in a liquid. The ORP readings represents how strongly electrons are transferred to or from substances in a liquid. Keeping in mind that the readings do not indicate the amount of electrons available for transfer.

This ORP Probe can be fully submerged in fresh water or salt water, up to the BNC connector indefinitely.

ENV-40-ORP ORP Probe Typical Applications
• Standard lab use
• Field use
• Soil
• Low ionic and ultra-pure water
• Strong reducing agents
• Samples containing heavy metals
• Hydroponics / aquaponics
• Beer, wine and other liquor
• Food safe
