Background
What is ORP?
Oxidation reduction potential(ORP) is a measure of the tendency of a chemical species to acquire electrons and
thereby be reduced. Reduction potential is measured in volts (V), or millivolts (mV). Each species has its own intrinsic
reduction potential; the more positive the potential, the greater the species' affinity for electrons and tendency to be
reduced. ORP is a common measurement for water quality. Electrical Conductivity (EC) is defined by the ability of a
solution to conduct an electrical current.
1. Introduction
Oxidation reduction is a process by which a molecule or ion loses or gains electrons. This occurs most readily in
water treatment and in pool and spa maintenance where an oxidizer, such as chlorine, is added to the water to
destroy contaminants. The higher the ORP value, the greater the sanitizing power of your water.
ORP-286 is ideal for swimming pools and spas and can provide a valuable indication of water quality.
This tester utilizes a platinum electrode and renewable cloth junction, that can be pulled out when clogging occurs,
reactivating the reference and restoring the electrode.
