DO5500 Transmitter
Dissolved Oxygen Controller / Transmitter
Designed for fermentation, medicine manufacturing, industrial dissolved oxygen analysis and control applications. With Clark cell mode and Galvanic cell mode selectable, and automatically compensates salinity / barometric pressure after manual input, it is advantageous for all demanding applications.
Features
NEMA4X, IP65 rated: waterproof and airproof. High protection against electromagnetic interference.
Large LCD, with high luminance LED orange backlight.
Automatically compensates salinity / barometric after manual input for increased accuracy.
Automatically compensates pipeline / depth pressure after manual input for increased accuracy.
Control modes: on / off limited control (LIT).
Separately adjustable high and low set-point hysteresis (dead bands) prevent chattering of relays around the set points.
Two level password protection prevents unauthorized tampering with settings.
Scaleable isolated 0/4 -20 mA Outputs.
RS-485 output.
