東亜ディーケーケー List of Products and Services

The "CGP-31" is a portable carbon dioxide concentration meter that employs a membrane-type carbon dioxide electrode based on electrochemical operating principles. Using the membrane glass electrode method, it is unaffected by the presence of other gases, except for volatile weak acids, acidic gases, and basic gases. Additionally, it is minimally affected by humidity, eliminating the need for dehumidification treatment. We also provide dedicated data collection software for importing measurement data into a computer in text format. 【Features】 ■ Adopts a membrane-type carbon dioxide electrode based on electrochemical operating principles, achieving high-precision CO₂ measurement. ■ Reduces preparation effort as dehumidification treatment is unnecessary. ■ Equipped with a concentration conversion function, making it easy to check and manage measurement values. ■ Allows switching settings between gas phase concentration (% (v/v)) and liquid phase concentration (mg/L), accommodating a wide range of measurements. ■ Features a memory function capable of storing up to 1000 measurement data points. *For more details, please refer to the PDF document or feel free to contact us.
