CARE AND USE

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

You can extend the life of your pH electrode in the following ways:

1. Always store with the cap full of buffer or storage solution MA9015 not water.
2. Clean your tester 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 tester in the sample for a faster result.
