DDG-3080 On-line Industrial Conductivity Meter

The DYDDG-3080 Industrial Conductivity Meter is a new-generation Chinese (English) microcomputer-based instrument developed by our company. It features a Chinese (English) display, Chinese (English) menu-driven operation, full intelligence, multifunctionality, high measurement accuracy, and strong environmental adaptability. It is widely applicable for continuous monitoring of conductivity values in solutions across industries such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

Instrument Features:
– New Panel Design: Cast aluminum housing with a metallic finish, creating a high-end E-era water analysis instrument.
– Full Chinese Display: User-friendly interface with multi-parameter simultaneous display, including conductivity, output current, temperature, time, and status on a single screen.
– High-Resolution Dot-Matrix LCD Module: All data, statuses, and operation prompts are displayed in Chinese (English), with no manufacturer-specific symbols or codes.
