The DDS-11 series (most commonly the DDS-11A) is a standard, benchtop digital conductivity meter widely used in laboratories and industries to measure the ionic strength and purity of aqueous solutions. It typically covers a measurement range from 0.00 μ S/cm to 199.9 mS/cm and features manual temperature compensation.
Key specifications and features of standard DDS-11A devices include:
- Accuracy: Typically ± 1.0% of the full-scale reading, utilizing a platinum black probe (such as the DJS-1C).
- Temperature Range: Manual temperature compensation usually spans from 10° C to 50° C, requiring users to input the solution’s temperature.
- Electrode Constants: Supports multiple electrode constants (0.01, 0.1, 1, and 10) to accommodate both ultra-pure water and highly conductive brines.
