HI-7021L 240 mV @ 25°C ORP Test Solution (500 mL)

HI-7021L is an ORP test solution designed for testing the precision of ORP Platinum and Gold electrodes within +/- 50 mV of 240 mV @ 25 C.

By simply immersing the ORP electrode in the test solution, users can quickly see if the electrode is reading accurately within the specified range. Using this as a diagnostic tool, users can clean and condition ORP electrodes, if necessary, to achieve correct measurements.

Each bottle has a Lot number and expiry date clearly listed.

All bottles have an air tight, tamper-proof seal to maintain the quality of the solution.

*A Certificate of Analysis is available on request.
