Hanna HI4105 Carbon Dioxide Combination

Hanna HI4105 Carbon Dioxide Combination Ion Selective Electrode (ISE)

The Hanna HI4105 Carbon Dioxide Combination is a gas-sensing combination ion selective electrode (ISE) specifically designed. This electrode combines convenience with precision, providing direct CO₂ measurements for environmental monitoring, water quality control, and biochemical research.

Key Features

• Gas-Sensing Combination Design: The HI4105 integrates a gas-permeable membrane, a sensing element, and a reference electrode into one compact, user-friendly body—no external components required.

• Targeted CO₂ Detection Range: It measures carbon dioxide concentrations from 1×10⁻² M to 1×10⁻⁴ M, equivalent to 440 to 4.4 ppm, making it suitable for a wide variety of applications from environmental testing to fermentation control.

• Optimized pH Operating Range: The electrode performs best in samples with a pH between 4.2 and 5.2, where dissolved carbon dioxide can be effectively and selectively detected.

• Stable Temperature Range: With an operational range of 0 to 40°C, the HI4105 offers stable performance under most lab and field conditions.

• Reliable Electrode Slope: Featuring an approximate slope of +54 mV per decade, the electrode provides predictable and reproducible response curves for quantitative analysis.

• Durable Delrin® Body: The chemically resistant and rugged Delrin® plastic housing ensures mechanical stability and long-term use in diverse environments.

• Easy Instrument Integration: The 1-meter coaxial cable with a standard BNC connector allows quick and secure connection to most ion meters and pH/mV meters.
