DDG-2080 Industrial Conductivity MeterDetailed product description：

The DDG-2080 industrial conductivity meter is a new generation of high-end instrument with Chinese language microcomputer, featuring full Chinese display, Chinese menu operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptability. It can be widely used for continuous monitoring of conductivity values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

Instrument features:
Full Chinese display, user-friendly interface, multiple parameters displayed simultaneously: conductivity, output current, temperature, time, and status are displayed simultaneously on one screen. Adopting a high-resolution dot matrix LCD display module, all data, status, and operation prompts are displayed in Chinese, without any symbols or codes defined by the manufacturer.
