FCL3500 Controller / Transmitter
FCL3500 Free Chlorine Controller / Transmitter
with pH Compensation
It is suitable for online measurement and control of disinfectant dosing in water industry,
swimming pool, water park, secondary water supply and other fields. Disinfection of medical
wastewater is not applicable due to complex componentswith pH Compensation
●128 * 64 dot-matrix LCD display, switchable in Chinese and English, IP65 protection level, all-weather stable operation
●simple menu design, simple and convenient operation, graphical prompt, beautiful and clear interface
●software digital filtering is adjustable, with enhanced hardware resistance to interference, making measurements more stable and adapted to complex industrial environments
●global access power supply 85~260VAC, but also customized DC model 18 to 36 V D C
●RS-485 digital interface, MODBUS-RTU communication protocol, read and write two-way communication, can achieve remote complete control of the instrument
●The residual chlorine and pH two parameters were measured simultaneously, and the compensation was calculated automatically
