Portable Carbon Dioxide Concentration Meter 'CGP-1' [Rental]

Portable Carbon Dioxide Concentration Meter 'CGP-1' [Rental]

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 widely usable both indoors and outdoors. 【Features】 ■ Dual use for liquid and gas phases The same electrode allows for the direct measurement of dissolved carbon dioxide (DCO2) in liquids and carbon dioxide (CO2) in gases. ■ 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 with high reliability Unlike methods such as the NOIR method, there is no need for a suction pump or carrier gas to deliver the sample (gas) to the detection area. Simply installing the electrode at the measurement location allows for the determination of the carbon dioxide concentration on-site. Additionally, there are no error factors due to variations in carrier gas flow rate. ■ Less susceptible to humidity effects ■ 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.
