Now Available with MODBUS/RS485 Interface & optional Titanium body

The Lumin-S optical dissolved oxygen sensor delivers reliable DO measurements over a long operating life. There are no membranes to replace, no electrolyte solutions to replenish, and no anodes to clean. Maintaining the sensor is as easy as replacing the optical sensing cap once every 1-2 years, and since all calibration data is stored on the cap, there’s no need to calibrate. This dissolved oxygen sensor outputs a Modbus/RS-485 digital signal for easy PLC integration.
