Use and Care
- Properly maintaining your ORP probe will give you fast, accurate results for longer.
- Here are our top three tips.
- Always store with the cap full of buffer or storage solution, not water.
- Clean your probe regularly by soaking it in the cleaning solution.
- Calibrate after cleaning and/or storage before testing to adjust for changes in the ORP probe sensor.
How do I Calibrate?
- The MW500 units come factory calibrated to read positive ORP. If you are looking to measure negative ORP readings, the best method is to let the probe tip sit in a small cup or jar of white distilled vinegar for a minimum of 4 to 5 days. This allows time for the tip to oxidize and read negative ORP appropriately. When the probe is not in use, the probe needs to be stored back in the white distilled vinegar.
