HI-7022L
Test the precision of an Oxide Reduction Potential (ORP) Electrode with Hanna Preparation and Pre-treatment Solutions.
The HI-7022L 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.
*A Certificate of Analysis is available on request.
