Product Description:

HZCN-1900Is a new generation of intelligent multi-parameter water quality analyzer.The analyzer uses advanced micro-controller as a control unit and advanced electronic circuit as an expansion module, the use of high-precision water quality sensor as a detection element, high sensitivity, fast response, stable performance. It can be used to measure any parameters such as PH, ORP, dissolved oxygen, residual chlorine, ozone, turbidity, suspended matter, sludge concentration and so on. It can be used to measure the parameters of the computer. Widely used: environmental protection, sewage treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmaceutical, fermentation, chemical, tap water and other multi-parameter on-line solution.

main feature:

• At the same time, the pH, ORP, dissolved oxygen, residual chlorine, ozone, turbidity, suspended solids, sludge concentration and other parameters were measured.
• Automatic / manual temperature compensation function.
• Communication function: With RS-485 communication interface (MODBUS protocol part of the compatible, optional), can be converted to RS-232.
• Optional on-line PC acquisition software, data acquisition and processing.
• 2 4-20mA output, 2 temperature detection.
• Automatic identification of standard solution, restore factory settings.
• Watchdog function: to ensure that the instrument will not crash.
• Power-off protection Protection> 10 years.
• Protection class IP65, waterproof moisture dust.
