DDG-2080 Industrial Conductivity Meter DDG-2080 Industrial Conductivity Meter is our new generation of all Chinese high-end microprocessor-based instrument, with full Chinese display, Chinese menu, all intelligent, high versatility, measurement performance, environment adaptability and other characteristics. Can be widely used for continuous monitoring of thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and running water, and the solution conductivity values. Instrument features: full Chinese display, user-friendly, multi-parameter simultaneously display: Display conductivity, output current, temperature, time and status on one screen at the same time. Using high-resolution bitmap-type LCD modules, all of the data, status, and operating tips are Chinese show no sign or code defined by the manufacturers themselves.
