ORP Volts refers to the Oxidation-Reduction Potential of vent fluid in units Volts. It measures the tendency of a vent fluid, and the chemical species within it, to acquire electrons (i.e. be reduced). The more positive the potential, the greater the affinity for electrons and tendency to be reduced. Used to calculate Vent Fluid Oxidation-Reduction Potential (ORP).
