PH5000 Controller / Transmitter
PH5000 pH / ORP Controller / Transmitter
User friendly, Large luminant LCD screen, easy operation, Symmetrical input, RS-485 output, High-end measuring technology ensures unbeatable precision and reliability at hazardous area applications. PH5000 is your professional choice.
●Designed for precise pH/ORP control at complex and harsh environment.
●High protection against electromagnetic interference.
●NEMA4X, IP65 rated: waterproof and anti-gas
●Multiple lines display of LCD screen, optional high luminance LED backlight
●Two relay circuits, users can select high-low control freely. Separately adjustable high and low
set-point hysteresis(dead bands) prevent chattering of relays around the set points.
●Third relay Cleaning/Alarm function; users can set the cleaning frequency and time
●Scaleable isolated 0/4-20mA Outputs for pH/ORP
●Two optional electrode input: balanced input or asymmetric input
●Temperature value offset adjustment
●Glass electrode and antimony electrode are selectable to meet different industrial situations or
HF(hydrofluoric acid) measurement situation
●Independent setting for process temperature(TST1) and calibration temperature(TST2) in manual
temperature compensation (MTC) mode.
