HI 7021M 240 mV @ 25°C ORP Test Solution (230 mL) is an ORP test solution designed for testing the performance of ORP electrodes.
When the ORP electrode is placed in the test solution the reading obtained should be within +/- 20 mV of the 240 mV @ 25°C value. This solution allows users to quickly see if their electrodes are reading correctly. Using this as a diagnostic tool, users can then decide if the ORP electrode needs to be cleaned and conditioned.
- Prepared with reagent grade chemicals
- Allows for a quick check of your ORP electrode
- Air-tight seal to ensure the quality of the solution
- Lot number and expiration date clearly marked on the label
