Dissolve Oxygen
Determine the levels of dissolved oxygen in water with a reliable and universal analytical indicator.
Companies use the universal UDA2182 indicator for its versatility in measuring conductivity, pH, ORP and dissolved oxygen. With its ‘mix-and-match’ input design, it offers unrivalled flexibility for a wide range of applications. Its common form, fit and function to older Honeywell analysers also enables a quick and easy retrofit into existing panels and installations.
Dissolved Oxygen Input
The dissolved oxygen input is from Honeywell’s unique equilibrium probe. It has these additional features:
● ppm or ppb Measurement
● Automatic or Manual Calibration
● Ambient Temperature and Atmospheric Pressure Compensation

Greater value and enhanced performance
These analysers or probe systems determine the levels of dissolved oxygen in water. The patented equilibrium dissolved oxygen probe design is unaffected by inert fouling or changes in flow conditions. The system’s analyser/controller measures either ppb DO levels in power plant and semiconductor applications for corrosion detection or deaerator efficiency or ppm DO levels in wastewater, environmental and process applications for control and compliance.
