  PH5500  pH / ORP Controller / Transmitter
Designed for precision pH / ORP control at complex industrial sites and unique housing design provides lower installation and cost and easy operation. PH5500 is your right Controller / Transmitter with Large LCD and high luminance LED orange backlight for easy reading.
 
 
● NEMA4X, IP65 rated: waterproof and airproof. High protection against electromagnetic interference.
● Two level password protection prevents unauthorized tampering with settings.
● NEMA 4X enclosure protects transmitter form harsh conditions.
● Two control modes: On / Off limited control (LIT), proportion pulse length control (PLC).
● Separately adjustable high and low set-point hysteresis (dead bands) prevent chattering of relays around the set points.
● Washing / warning relay.
● Scaleable isolated 0/4 -20 mA Outputs for pH/ORP.
● Independent setting for process temperature (TST1) and calibration temperature (TST2) in manual temperature compensation (MTC) mode.
