CON3500 Controller / Transmitter
CON3500 Conductivity / TDS / Salinity
It is suitable for accurate measurement of conductivity, salinity, total solid dissolution in harsh
climate and complex industrial environment.
●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 VDC
●RS-485 digital interface, MODBUS-RTU communication protocol, read and write two-way communication, can achieve remote complete control of the instrument
●Three measurement modes CON (conductivity) SAL (salinity) or TDS (total dissolved solids)
