• Use with RDOX optical dissolved oxygen sensors

The 7300w2 controller allows for local calibration and datalogging, while providing power to the RDOX optical dissolved oxygen sensor (94750). Controller displays measurements from up to two directly connected sensors. Three relays control alarms, lights, pumps, valves or other process control devices. Two scalable 4-20 mA outputs, Modbus communication, and a USB port for logged data retrieval are standard. Optional expansion modules add up to six more sensors or even extended output signal capability; contact our Technical Specialists for expansion module ordering details.

For a complete DO system, order this controller and an RDOX sensor (94750).
