Characteristics and Applications of DDS-307A Laboratory Conductivity Meter

DDS-307AThe laboratory conductivity meter adopts microprocessor technology and dual display function of blue or white backlit LCD, which simultaneously displays the conductivity and temperature values of the measured solution; It can also automatically switch the measurement range and directly read the measurement value. It is an essential instrument for measuring the conductivity of aqueous solutions in laboratories. It is widely used in industries such as petrochemicals, biomedicine, sewage treatment, environmental monitoring, mining and smelting, as well as in colleges, universities and research institutions. If equipped with appropriate constant conductivity electrodes, it can be used to measure the conductivity of pure or ultrapure water in electronic semiconductors, nuclear energy industry, and power plants. There is an RS-232C interface, which can be connected to a TP-16 printer to instantly print measurement results or communicate with a PC.
