The Adwa AD3000 is a professional laboratory conductivity, TDS and temperature bench meter designed for accurate water quality measurement and routine laboratory analysis. It combines a wide measurement range, automatic temperature compensation, flexible calibration options, GLP functionality and data storage in a reliable benchtop design.
The AD3000 measures electrical conductivity from 0.00 µS/cm up to 199.9 mS/cm across multiple automatically selected ranges. Its TDS measurement range extends from 0.00 ppm to 99.9 ppt, allowing the meter to be used for different water-quality and laboratory applications.
The meter features a selectable TDS conversion factor from 0.40 to 1.00, with 0.50 as the default value. Conductivity calibration includes zero-point offset calibration and one-point slope calibration using memorized standard values or a custom calibration value.
Temperature can be measured from -9.9 to 120.0°C with a resolution of 0.1°C. The supplied AD76309 EC probe includes a built-in temperature sensor for convenient measurement and temperature compensation.
The AD3000 can store up to 250 on-demand samples, making it useful for laboratory testing, quality control, water treatment and other applications requiring conductivity and TDS monitoring.
