ORP / Redox calibration solution (ZoBell's solution)
SKU: 2316949
Manufacturer: Hach
Availability: Order only
Solution for calibration and accuracy verification of ORP electrodes. When compared with a standard solution, the reading on the ORP meter should be within ± 10 mV.
Zobell's solution shows a temperature correlation between 0 - 30 °C. The value depends on the type of reference electrode, temperature and concentration of the filling solution.
Typical ORP at 20 °C: 228 mV when measured with an Ag / AgCl reference electrode.
