This product represents a new generation of intelligent water quality detection instrument that has been independently developed and refined through our company's extensive research and engineering efforts. The device incorporates a comprehensive suite of advanced technological features including dual-language menu interface supporting both Chinese and English operational protocols, remarkable stability characteristics across varying environmental conditions, superior repeatability performance in consecutive measurement cycles, and extensive multi-functional capabilities designed to address diverse water analysis requirements.
Main features:
◇ Large-screen liquid crystal display, menu operation in Chinese and English, and simultaneous display of multiple parameters.
◇ Communication function: RS-485 communication interface (Modbus-RTU protocol partially compatible).
◇ Factory settings can be restored.
◇ Watchdog function: ensures that the instrument will not crash.
◇ Power-down protection＞10 years.
◇ Core components are from foreign brands.
◇ Protection class IP65, waterproof, moisture-proof and dust-proof.
