CARBOTEC NIR is a very precise, optical carbon dioxide sensor for measurement of “true” CO2 content in beer and beer-based mixed drinks. Dissolved CO2 has a major impact on the quality and taste of the product.
For continuous measurement of dissolved carbon dioxide in liquids, CARBOTEC NIR is perfectly suited. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and almost maintenance-free. The new generation of CARBOTEC NIR sensors is based on Attenuated Total Reflection (ATR) technology. Near infrared (NIR) light is transmitted through a sapphire crystal. The NIR light reflects several times on the inner surfaces of the crystal, while the outer surfaces are in contact with the carbonated liquid. Since CO2 molecules absorb the specific wavelength of the transmitted light, each reflection decreases the intensity according to the CO2 content in the product. The sensor provides the “true” carbon dioxide content, as quantified by the NIR absorption. The measurement result is neither influenced by other gases in the product not by its colour, turbidity and viscosity. Due to the absence of moving parts, the instrument is virtually maintenance-free. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt100 sensor.
