Carbon Dioxide Combination Ion Selective Electrode (ISE)

The HI4105 is a gas sensing, combination ion selective electrode (ISE) for the determination of carbon dioxide (CO₂) in solution. Its PTFE membrane allows for carbon dioxide gas diffusion into a thin layer of internal electrolyte. The internal sensing elements are within a durable Delrin® body.  The HI4105 is ideal for a variety of applications including water, beverage, and wine applications.

• Replaceable PTFE membranes
• Durable Delrin® body
• Detection from 17.6 to 880 mg/L CO₂
