HI-7022M ORP test solution, 470mV, 230 mL bottle

The HI-7022M is an ORP Solution for Platinum and Gold Electrodes and reads 470 mV at 25°C.

ORP standard solutions allow you to test the precision of ORP electrodes. For example, by immersing the electrode in HI-7022 solution, you should read 470 mV at 25°C.

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.

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.
