DS380 series of fluorescent dissolved oxygen sensors use a new generation of fluorescence lifetime technology and high-performance fluorescent materials. No oxygen consumption, No flow rate limitation, no electrolyte, no maintenance and calibration, no interference from hydrogen sulfide, and excellent stability. Built-in temperature sensor, automatic temperature compensation. An RS485 output can be networked without a controller.
