Tuneable Diode Laser Absorption Spectroscopy TDLAS Hygrometer

TDLAS hygrometers are advanced measuring instruments specifically designed to determine moisture levels with exceptional accuracy. They are widely used in applications that necessitate precise moisture monitoring, including environmental monitoring, industrial processes, and research and development.

How TDLAS Hygrometers Work

TDLAS hygrometers employ a specialized technique known as tuneable diode laser absorption spectroscopy. This method involves directing a laser beam through a sample of gas, and then measuring the absorption of light energy at specific wavelengths that correspond to the presence of water vapor. The amount of absorption is directly proportional to the moisture concentration, enabling highly precise measurements.

Key Benefits of TDLAS Hygrometers
