Hach, 3650EX/111, Orbisphere 3650Ex ATEX portable analyzer for dissolved Oxygen (O₂), battery powered, units:ppm/ppb or ppm only

The portable ATEX system
The Orbisphere 3650 EX portable analyzer family measures oxygen (O2) or hydrogen (H2) in areas where hazardous and flammable conditions are possible.
It displays continuous line sample measurements and logs the results internally for review later. It can be used for liquid (dissolved) or gaseous samples, and a special “dual-use” is available for oxygen.
When coupled with a choice of membrane covered, electrochemical sensors, the Orbisphere 3650 EX is suitable for sampling and measuring dissolved concentrations from trace ppb to super saturation and gaseous concentrations from ppb to percent (%) levels.
This item is IECEx certified. What is IECEx: The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety.
