Optical Dissolved Oxygen System

The SMART2-OPTO optical dissolved oxygen sensor operates based on luminescent optical technology and is compliant with ASTM International Method D888-05. With no calibration requirement and ultra-low power consumption, it is ideal for field work and both short- and long-term campaigns. It provides accurate measurements without oxygen consumption, especially in very low oxygen conditions. The sensor stores calibration and history data internally, enabling a true plug-and-play experience without recalibration. Thanks to the Universal Modbus RS485 protocol, it can be easily integrated with dataloggers, controllers, and remote monitoring systems.The SMART2-OPTO optical dissolved oxygen sensor operates based on luminescent optical technology and is compliant with ASTM International Method D888-05.
