Dissolved Oxygen Meters

Dissolved oxygen meters determine dissolved oxygen saturation and biological oxygen demand (BOD) in water and other aqueous solutions . Available in benchtop or portable instruments, sensors, and probes, these meters offer flexibility and save valuable laboratory space. Thermo Scientific™ Orion Star™ A223 Dissolved Oxygen and RDO Portable Meters record reliable dissolved oxygen and temperature measurements for a large range of applications in the field.
