Dissolved Oxygen Probes
At Thomas Scientific, we have a great range of optical do probes, DO membranes, and Multiparameter Meters to accommodate a range of laboratory requirements. Some even offer suitability within the field environment.
Dissolved oxygen sensors are manufactured robustly and carry extensive memory functions. The helpful features of a three-color backlight (waterproof and floating in the water) can provide extra time and ensure ultimate efficiency when dealing with complex systems and measurement setups to achieve clear, accurate readings.
