ICAD（Iterative CAvity enhanced DOASIterative cavity enhanced differential absorption spectroscopy technologyNO₂/NO_x/NOmeasurement systemWithin the spectral range of~430-465 nmInternally adoptedDirect optical absorption spectroscopy. By measuring absorption spectra and applying themICADAlgorithms can directly identifyNO₂Unique feature absorption structure, and combines it with water vapor（H2O）Or formaldehyde（CHOCHO）Wait for other overlapping absorption to distinguish. Make it have direct measurement capabilityNO₂The advantage is that it does not interfere with other substances and does not require the introduction of new interferences(For example)CLD，CRD，CAPS）The drying mechanism. due toICADThe system does not rely on absolute strength, but on characteristic differential absorption structures, thereforeThere is no absolute zero drift, and the system is insensitive to temperature changes, vibrations, and light source attenuation. Therefore, it is suitable for long-term or mobile measurement. At the same time, the system passes throughNO→NO₂Internal converter based on gas-phase titration（GPT）(optional) can also be measuredNO_x/NOThis instrument does not require gas consumption and is easy to operate. The data display can be directly used forWiFiperhapsLANEquipment.
