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 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.
