Integrated design
Low maintenance volume
Residual or total chlorine monitoring using the classic DPD method
ZMING HQ-1002 Water Quality Monitoring System for Water Supply Network is a multi-parameter online water quality analyzer developed specifically for the online monitoring needs of water supply network water quality. It can continuously monitor water quality parameters such as residual chlorine, total chlorine, turbidity, pH, temperature, ORP, conductivity, etc. It is perfect for secondary water supply, swimming pool water quality monitoring, and other occasions.
Application Fields:
l Monitoring of drinking water pipeline network
l Secondary water supply monitoring
l Swimming pool water monitoring
l Water quality monitoring of centralized water supply facilities in rural areas
l Process water monitoring in waterworks
Technical Features:
Ø Integrated design: It adopts an integrated design with a small footprint and supports wall and vertical installation. It can continuously monitor water quality parameters such as residual chlorine, total chlorine, turbidity, pH, temperature, ORP, conductivity, etc
Ø Low maintenance: Specially designed for unmanned applications, with automatic cleaning and automatic sewage discharge. Automatic flow recognition, stop water and measurement. Power outages can be automatically restored. Water and electricity separation design, leakage alarm, adjustable residual chlorine measurement cycle, ensuring adjustable reagent replacement cycle within 1-12 months.
Ø Classic measurement method: DPD classic method is used for residual or total chlorine monitoring, and electrochemical electrodes such as pH, ORP, and conductivity can be configured according to requirements. It can also expand indicators such as TOC and chromaticity
Ø Complete communication functions: RS485 digital output and optional multi-channel 4-20mA output, convenient for users to transmit data to the monitoring center; Multi way relay for early warning output, with free setting of upper and lower warning limits.
