Test the precision of an Oxide Reduction Potential (ORP) Electrode with Hanna Preparation and Pre-treatment Solutions.

The standard solutions are perfect for immersing the electrode and establishing initial readings which should fall within the 200 to 275 mV range at 25 C/77 F, for example, or within the parameters you are testing.

If the reading is outside the indicated range, clean and condition the ORP Electrode in Hanna pre-treatment solution. Use HI-7092 for oxidising or HI-7091 for reducing pre-treatment.

Hanna's extended description

HI-7021M 240 mV @ 25°C ORP Test Solution (230 mL)

HI-7021M 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.
