Dissolved oxygen analyzer


Accurate and reliable measurement of dissolved oxygen in high purity water.

The Navigator 500 dissolved oxygen analyzer provides continuous monitoring and control of dissolved oxygen levels in steam-raising and desalination plants and semiconductor water treatment.



Featuring a separate sensor section and transmitter, the Navigator 500 Dissolved Oxygen gives users the option of adding up to four wet-sections to one transmitter, enabling measurement of samples from different measuring points. This not only offers an economic and compact solution, but allows operators to mix and match other parameters within the Navigator 500 range to reduce installation footprint and cost.
