FCL5500 Controller / Transmitter
FCL5500 Free Chlorine Controller / Transmitter
At different pH values, Chlorine forms different species in water. For a reliable free chlorine measurement, it's necessary to take pH and temperature compensation into account.
●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
