 Milwaukee pH600AQ Manual


All pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH Pen will give you fast, accurate results for longer.

Here are a few tips: 

  1. Always store upright with the cap full of buffer or storage solution MA9015, not water.
  2. Clean your Pen regularly by soaking in cleaning solution MA9016.
  3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.
  4. Gently stir the Pen in the sample for a faster result.
