CH2O Laser Gas Sensor-LAS Gas Sensor-Shanghai Pidtek Intelligent

CH2O Laser Gas Sensor

CH2O Laser Gas sensor is based on Quantum cascade laser (QCL) technology, the ultra-narrow linewidth of QCL laser is used to accurately select the high intensity absorption spectrum line of formaldehyde molecule in the mid-infrared band, so as to achieve high selection, anti-interference and high-precision measurement of formaldehyde molecule.
