Main highlights

Very high accuracy of +/- 3 MV – at the specified temperature of 25 °C, the solution has a standard deviation of only 3 mV. An accuracy check takes place with each batch and is certified in the batch certificate.
No mixing required – the Redox calibration solution is ready to use and does not need to be mixed with distilled water, as is the case with calibration powders. We recommend tilting the solution into a separate glass for calibration and then not returning it to the bottle to avoid contamination.
Made in Germany – Our Redox calibration solution is produced under strict quality standards in Germany. Each batch undergoes extensive testing in a specialized laboratory to ensure consistent quality and highest precision.
Compatible with all standard Redox measuring devices – the solution is universally applicable and is suitable for calibrating electrodes of almost all brands, regardless of the manufacturer.
Batch certificate for downloading: specifying the batch number printed on each solution, the batch certificate can be downloaded after purchase. This confirms the quality, traceability and accuracy of the solution.
