CAUTIONS
•
The pH membrane is made of special pH glass. This is somewhat fragile. Do not touch the
membrane or press this onto a hard surface. This meter is for measuring pH in a liquid
solution.
•
If testing food, test a sample only and then discard the sample, do not place this meter directly
into the product. Test the surface of the sample and do not press into the sample.
•
This meter is not for use on concrete.
•
In case the device is going to be unused for an extended period of time, remove the batteries
to prevent them from draining or leaking.
