Real Tech’s Dissolved Oxygen (DO) sensor uses a luminescent optical technology approved by the ASTM International Method D888-05. The compact and robust sensor requires no calibration and very minimal power. Without oxygen consumption, the sensor allows for accurate measurement in many applications, especially those with very low oxygen concentrations.
