Our organization has independently engineered a contemporary water quality analysis instrument that represents a significant advancement in detection technology. This system incorporates dual-language interface capabilities supporting both Simplified Chinese and English menu navigation, enabling operators from different linguistic backgrounds to interact with the device effectively. The instrument demonstrates exceptional operational reliability characteristics combined with reproducible measurement outcomes and comprehensive analytical functionality that addresses multiple testing requirements within a single platform.
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.
