On-line CO2 Analyzer model CARBOTEC NIR

Analyzer for continuous measurement of dissolved carbon dioxide in liquids.

Measurement system:

Infrared absorption (NIR) with attenuated total reflection technology (ATR)

The sensor, in contact with the sample directly, has a sapphire crystal in which the infrared light is reflected several times on the surface, as the CO2 molecules absorb at a specific wavelength, the intensity measurement is proportional to the content.

• Quantitative measurement of the true CO2 content
• Not influenced by other gases.
• No moving parts.
• Automatic temperature compensation.
• CIP resistant.
• Sanitary execution.
• Maintenance free
