Go Direct ORP
(Order Code GDX-ORP)
Go Direct ORP measures the ability of a
solution to act as an oxidizing agent or
reducing agent. ORP stands for oxidation-reduction potential. For example, ORP
electrodes are often used to measure the oxidizing ability of chlorine in
swimming pools, or to determine when the equivalence point has been reached
in an oxidation-reduction reaction.
