Zobell ORP Calibration Solution

Use Zobell solution to verify the performance of your ORP electrodes—ideal for use with Ag/AgCl or saturated calomel electrode systems. Reagent is available in dry form only and must be reconstituted prior to use. Reconstitution is simple—add 125 mL of deionized or distilled water to bottle, shake, and use. Bottle label has a place to write the expiration date to guarantee freshness. Redox potential value for Ag/AgCl electrodes is 231 ±10 mV. Redox potential value for saturated calomel electrodes is 185 ±10 mV

ORP Standards

These stable, ready-to-use standards require no mixing and contain no organics or hazardous chemicals—use straight out of the bottle. Use these standards as your relative mV standard and calibrate the offset of your sample. Redox potential values are 215 mV for Ag/AgCl reference electrodes and 420 mV for standard hydrogen reference electrodes.
