Universal Disinfection Residual Chlorine Controller Used Under 4 ~ 9pH
Introduction
In the water treatment process, chlorination disinfection is an important part of water quality control in water plants. The DRFN's ADS2-U3D-CS4 residual chlorine controller is a single-parameter instrument, it is connected to the residual chlorine sensor to realize the measurement of the chlorine.
Advantages Of The Residual Chlorine Controller
1. A 128*64 black and white graphic dot matrix screen, the display backlight provides constant light and energy-saving mode selection.
2. All the configuration entered by the user is kept indefinitely, even if there is no power, the data will not be lost.
2. Record the user's maintenance details of the equipment, the calibration effect of the diagnostic sensor, and will give corresponding prompts for inaccurate calibration instruments.
3. Two-wire RS485 interface, the communication protocol is MODBUS RTU, support JSON text data format.
4. Menu password can be set to facilitate hierarchical management;
5. The residual chlorine meter has clock and historical data recording functions to meet higher data management requirements.
6. Support a variety of installation methods and can be applied to more different installation environments. The enclosure protection level is IP66.
