1.2 Product Description
The Corning Model 311 is a multi-range, water
resistant, Conductivity Meter with automatic
temperature compensation. The sensors in the
meters probe utilize the latest technology in
conductivity measurement. The four-ring
potentiometric method incorporated into the probe
has been proven to provide higher accuracy than
the more common amperometric method. The
Model 311 has a range of 0 to 199,900 µS/cm and
can be used in any sample from treated water to
brine. The temperature of all conductivity
measurements are automatically compensated for
by the meters ATC circuitry. The probe is easily
detached and can be changed without having to
be returned to the factory.
