This product is a new generation of intelligent water quality detector independently developed by our company, featuring Chinese/English menu operation, high stability, superior repeatability and multi-functionality, etc. It can accurately measure the value of acid and alkali concentration in solution. Widely used in: environmental protection, sewage treatment, thermal power, breeding, food processing, printing, metallurgy, pharmaceuticals, fermentation, chemical industry, tap water and other solutions in the acid and alkali concentration of the on-line detection.
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.
