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

Consen Engineering Pte. Ltd.

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.

Gas Analyzer

Accurate Analysis of Binary Gases

The Honeywell 7866 Thermal Conductivity Analyzer is designed to provide a highly sensitive and accurate analysis of a binary (2- component) mixture of gases. It can be calibrated to measure a single component of a multicomponent gas mixture, providing the background gasses constitute a stable mixture (such as air), or have approximately the same thermal conductivity.
