HI7022L is a quality ORP test solution made from reagent grade chemicals and used to test platinum and gold ORP electrodes. Hanna test solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution.
- Prepared with reagent grade chemicals
- Allows for a quick check of your ORP electrode
- Air tight bottle with tamper-proof seal to ensure quality
HI-7022L is an ORP test solution designed for testing the precision of ORP Platinum and Gold electrodes within +/- 50 mV of 470 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.
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.
