If you are using a multimeter on the ohms range to measure the conductivity
of your solution you may be putting yourself in harms way.  These meters use
a DC source voltage for resistance measurements, usually a 9 volt battery.
This is enough voltage to start the process of electrolysis from one probe
to the other.  I believe that most of these probes are nickel plated.
Nickel ions are very bad for you.  A proper conductivity meter uses a
relatively low AC voltage at 400 cycles ore more to eliminate the very
phenomena.
