Система бесхлорной мутности интегрированная онлайн Многопараметрическая тестер качества воды для городской подачи

DR4500 drinking water on-line multi-parameter analyzer is a system integrating pipe network water quality monitoring sensor, data processing unit, internal water flow pipeline unit, wireless transmission control, etc. It can continuously measure temperature, PH, turbidity and disinfectant indexes, and can expand water quality parameters such as conductance and ORP.

Key Features

DR4500 drinking water online multi-parameter analyzer consists of sensor unit, transmitter unit, touch screen interface and lightning protection and leakage protection. In addition, water intake control unit, automatic cleaning unit, wireless transmission unit, leakage alarm unit and remote data center can be selected to meet the actual needs of the site. The product has the following characteristics:

l  All sensors and display transmission units are integrated in a 700*520*300 box. Highly integrated, reserved standard water inlet and outlet interfaces, on-site plug and play.

l  The internal structure is designed with a pressure regulating module and a flow stabilizing defoamer to ensure stable water flow at the sensor end Fixed, it is less affected by the pressure change from the pipe network.

l  Real-time measurement mode is standard, and interval measurement can be adopted when ordering and selecting water intake control unit.

l  The automatic cleaning unit can be ordered and selected to ensure the long-term reliable operation of the monitoring instrument.

l  The water leakage alarm unit can be ordered and selected to detect whether there is any water leakage fault inside the instrument and to be used by bees Sound the alarm.

l  It has the functions of historical data record and query. It has the functions of power-off protection and automatic recovery of incoming calls, and the parameters set after power-off are not lost. It has the functions of automatic alarm and recording of abnormal data, such as ordering. The alarm can be displayed on the remote monitoring computer or sent to the mobile phone set by the user.

l  7-inch touch screen and the all-English operation interface are simple and clear, simple and easy to learn.

l  The modular design of the analysis instrument can easily realize the subsequent expansion of functions without major changes, which is convenient for customers to control the water information in all directions. (e.g. Additional information such as ORP, conductivity, water pressure, etc.).

l  The box is made of SS304, with good corrosion resistance. The interior is designed to separate water and electricity and dry and wet.

l  The instrument fully considers EMC interference in frequency converter environment.
