The dissolved carbon dioxide (DCO2) in the liquid and the carbon dioxide (CO2) in the gas can be directly measured using the same electrode.
The adoption of the diaphragm glass electrode method enables measurements in both liquid and gas phases. It allows for the direct measurement of dissolved carbon dioxide (DCO2) in liquids and carbon dioxide (CO2) in gases using the same electrode. Its compact and lightweight design, along with easy maintenance and handling, makes it suitable for a wide range of applications both indoors and outdoors. 【Features】 ■ Dual use for liquid and gas phases Direct measurement of dissolved carbon dioxide (DCO2) in liquids and carbon dioxide (CO2) in gases can be performed using the same electrode. ■ Capable of measuring small samples The carbon dioxide electrode (diaphragm glass electrode method) does not consume the sample. Therefore, it can measure small samples and can be inserted into soil, powders, or granular materials for measurement. ■ Direct measurement. High reliability Unlike methods such as NOIR, there is no need for a suction pump or carrier gas to deliver the sample (gas) to the detection area. By simply installing the electrode at the measurement site, the carbon dioxide concentration at that location can be determined. Additionally, there are no error factors due to changes in the flow rate of the carrier gas. ■ Less affected by humidity ■ Automatic temperature compensation The temperature characteristics of the electrode are automatically compensated over a wide range of 5 to 50°C. The carbon dioxide concentration at the measurement temperature can be determined quickly and accurately.
