DDG-3080 Industrial Conductivity Meter
DDG-3080 Industrial Conductivity Meter is our company's latest top-class instrument equipped with a microprocessor and
complete English menu. It has display and menu operation pattern; it is characterized by its intelligent operation, multi-function
and high measuring performance and its strong environmental adaptability. It can be widely used for continuous monitoring of
the conductivities of solutions used in the following fields: thermal power plant, chemical fertilizer, chemical industry, metallurgy,
environmental protection, pharmacy manufacturing, biochemistry, foodstuff and running water.
Features
| It has a complete English display and friendly interface. Various parameters can be displayed at the same |
| time: conductivity, output current, temperature, time and status. Bitmap type liquid crystal display module |
| with high resolution is adopted. All the data, status and operation prompts are displayed in English. There |
| is no symbol or code that is defined by the manufacturer. |
