The CARBOCAP® Technology Optical, infra-red measurement technology Single-beam, dual-wavelength NDIR technology

The amount of infrared light passing through the gas is measured at two discrete wavelengths: the absorption wavelength (4.3 µm), where CO2 absorbs strongly the reference wavelength (3.9 µm), where CO2 has no absorption

2nd-Generation CARBOCAP® TechnologyMiniature filament light bulb replaced with a

microglow – a micromechanical component manufactured by Vaisala Compared to a filament lamp it has: Longer lifetime: >15 years Low power consumption Stable light output Fast response at startup Single-beam, dual-wavelength NDIR measurement

technology in a compact structure

CARBOCAP® technology with continuous internal referencing1. Reliability

– Only one light source and one detector - and a tunable filter - needed

2. Stability– Tunable filter enables measuring continuously a CO2

signal and a reference signal – ensures a stable measurement in all conditions

3. Tolerates harsh environments– Due to internal referencing minimal maintenance in harsh

environments is needed
