DDG-2080 Industrial On-line Conductivity Meter – Doryang

The DDG-2080 Industrial Conductivity Meter is our company’s new generation of fully Chinese microcomputer-based instruments. It features a fully Chinese display, Chinese menu-driven operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptability. It is widely applicable for continuous monitoring of conductivity values in solutions across various industries, including power plants, thermal power stations, chemical and fertilizer plants, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

Instrument Features:
– Fully Chinese display and menu-driven operation, with multiple parameters displayed simultaneously: conductivity, output current, temperature, time, and status on a single screen.
– Utilizes a high-resolution dot-matrix graphic LCD module. All data, statuses, and operation prompts are displayed in Chinese, without any manufacturer-defined symbols or codes.
