HANNA Oxidation-reduction potential calibrating fluid (ORP) 240mV/500mL

HI7021L Redox potential test solution is designed to measure the performance of ORP electrodes. When placing the ORP electrode in this test solution, the reading value should be within the ±20 mV range of 240 mV @ 25°C. This solution allows the user to quickly check if the electrodes are working properly and can be used as a diagnostic tool to determine if the electrodes need to be cleaned and conditioned. HI7021L are manufactured with reagent-grade chemicals and in a temperature-controlled environment, and the bottles are labeled with product code, lot number, and expiration date, and are equipped with tamper-evident seals to ensure the quality and freshness of the solution.
