Parameter measurement is diverse:
The standard version can measure turbidity, residual chlorine/chlorine dioxide pH, Temperature monitoring, customized version can flexibly adjust conductivity/TDS, dissolved oxygen, ORP and other parameters according to customer needs, suitable for online water quality monitoring in various scenarios such as urban or rural water plants, water supply networks, secondary water supply, user terminals, indoor swimming pools, large water purification equipment and direct drinking water.
Accurate and reliable measurement:
The measurement accuracy of various parameters is excellent, such as turbidity measurement accuracy of up to 2% or ± 0.02 ntu (different ranges vary); The measurement accuracy of residual chlorine/chlorine dioxide is ± 0.05 mg/l or ± 5%; The pH/ORP accuracy is ± 0.1 pH, ± 20 mV (ORP), or ± 2%. At the same time, the stability of each parameter indication is ≤ 1.5%, which is stable for long-term operation and can continuously output reliable measurement data.
Quick response speed:
The response time for various parameters is short, with turbidity T90 ≤ 120 seconds, residual chlorine/chlorine dioxide ≤ 120 seconds, pH/ORP ≤ 60 seconds, conductivity ≤ 30 seconds, dissolved oxygen ≤ 30 seconds. It can quickly feedback changes in water quality parameters and transmit information to monitoring personnel in a timely manner.
Good environmental adaptability:
The working temperature is between 4 ºC and+50 ºC, and a temperature controlled heating and antifreeze module with -25 ºC to+50 ºC can be optionally selected. The working humidity is ≤ 95% RH (no condensation), and the protection level is high. It can work stably in various harsh environments.
Powerful communication function:
equipped with RS485 ModBus RTU communication protocol interface and wireless interface, it facilitates data transmission and communication with other devices or systems, achieving remote monitoring and data management purposes.
Easy installation and maintenance:
The installation process is simple and does not require strict on-site conditions. The maintenance cycle is relatively long, for example, the recommended maintenance cycle for turbidity is 3-12 months, while for residual chlorine/chlorine dioxide it is 1-3 months or calibrated weekly, and consumables are replaced every 3-6 months, reducing maintenance costs and workload.
High degree of customization:
The customized version can customize the instrument appearance, logo, system name and other items according to customer needs, and can also flexibly adjust monitoring parameters to fully meet the personalized needs of different users.
