Keep your ORP Meter and ORP Electrode measuring accurately with our certified ORP calibration solution. ORP electrodes are part of pool dosing systems, where the measurement is used to dose and measure the chlorine present in the water. ORP is fairly stable, but it does require a good calibration at regular intervals. 

Our ORP Calibration Solution is produced in accordance with the highest international standards and norms, DIN and NIST. They include a certificate of Analysis and SDS (Safety Data Sheet).

Our ORP Buffer Solution is compatible with any brand of ORP Electrode of ORP meter available on the market.
