Digital Online Chlorine Dioxide Controller RS485 For Swimming Pools Disinfectant
Product Introduction
Chlorine dioxide disinfectant is an internationally recognized high-efficiency disinfectant. It is very safe and has no residual toxicity. With the widespread application of chlorine dioxide as a disinfectant, it is very important to detect and control its concentration. DRFN’s DUC2-CD-H chlorine dioxide controller is used for the measurement of chlorine dioxide. It is a digital meter, which can be connected to DRFN’s digital chlorine dioxide sensors.
Features Of The Chlorine Dioxide Controller
● RS485 interface, MODBUS RTU communication protocol
● Time and historical data recording function
● 128*64 large LCD screen, adjustable backlight mode
● Power-off protection configuration, parameters can be kept indefinitely
● A variety of installation methods: wall, pipe clamping, and panel installation
● 2 settable 0/4~20mA active current loop outputs
● Provide AC or DC power supply mode, both of which are wide-voltage power supply
Applications Of The Chlorine Dioxide Controller
● Disinfection Systems
● Cooling Towers
● Water Treatment
