AD330 is a heavy-duty portable microprocessor-based
instrument for measuring conductivity, TDS and
temperature.
The autoranging feature of the EC and TDS readings
automatically sets the instrument to the scale with the
highest resolution.
Measurements are compensated for temperature effect
automatically (ATC) or manually (MTC).
The temperature compensation feature can also be
disabled to measure the actual conductivity.
The temperature coefficient is user selectable.
The instrument also features a measurement stability
indicator, GLP capability, and a user selectable ID
code to uniquely identify the instrument.
