DDG-2080 conductivity meter is our company’s latest top-class instrument equipped with

a function and high measuring performance and its strong environmental adaptability. 

It has a complete English display and English menu operation, 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.

 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.
