ADWA AD310 Standard Professional Conductivity-Temperature Portable Meter


Auto-Ranging feature that sets the instrument to the scale with the highest resolution; Measurement stability indicator

  • Parameters: EC(Conductivity), Temperature


AD310 is a portable microprocessor- based instrument for measuring EC, and temperature. The auto ranging feature of the EC 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. The temperature coefficient is user selectable. The instrument also features a measurement stability indicator.
