DDB-303A Conductivity Meter
DDB-303A conductivity meter is a laboratory instrument to measure the conductivity of aqueous solution. It is widely used in petrochemical, biological medicine, sewage treatment, environmental monitoring, mining smelting and other industries and colleges and universities and scientific research units. It can also be used to measure the conductivity of pure or ultra-pure water in electronic semiconductors, nuclear power industry and power plants with appropriate constant conductance electrodes.
