Our OAKTON 1000 series 1/4 DIN dissolved oxygen controller features
independent 100% and zero adjustment calibrations and offset adjustment
capabilities to ensure high accuracy for your exact conditions. Its 0 to
2000 second selectable time delay and adjustable set point hysteresis
bands means you can tailor control relay action to your specifications.
Each unit is selectable for isolated 0-20 or 4-20 mA
transmitter/recorder output; 110 or 220 VAC; normally open or closed
relays; and manual or automatic temperature compensation. The compact
1/4 DIN size fits into standard panel cutouts. The IP54 rated front
panel keypad is weather resistant. Includes mounting hardware.
