Go Direct Optical
Dissolved Oxygen
(Order Code GDX-ODO)
Go Direct Optical Dissolved Oxygen is a luminescence-based dissolved oxygen
probe that can also measure water temperature and atmospheric pressure. It is
actively measuring temperature and pressure, so there is no need for calibration.
This probe can be used in experiments to test water samples in the field or in the
laboratory.
