Optical hygrometer
WebAbstract An optical hygrometer based on the differential absorption of the H Lyman- α line has been designed and built for use in atmospheric field studies. The absorption is determined along two separate paths containing sample and dry reference air, respectively, hence eliminating undesired absorption by O 2. Web1 day ago · Optical hygrometers are used to measure the absorption of light by water. All this process is based on identifying the moisture in the air. Two components are there, …
