NH3 Laser Gas sensor
NH3 Laser Gas sensor

NH3 Laser Gas sensor is based on Quantum cascade laser (QCL) technology, the ultra-narrow linewidth of laser is used to accurately select the high intensity absorption spectrum line of ammonia molecule in the mid-infrared band, so as to achieve high selection, anti-interference and high-precision measurement of ammonia molecule.
