Part 5: Applications of Chilled Mirror Hygrometers

Part 4: Operating Principles of Chilled Mirror Hygrometers

Part 3: Humidity UnitsA chilled mirror hygrometer measures the dew or frost point in a gas mixture of water vapor and a carrier gas. The measurement is performed automatically through opto-electronic means. The various definitions of humidity are…

Part 2: Chilled Mirror Hygrometry (CMH) The humidity content of a gas is a critical measurement and control parameter in many industrial processes and laboratory operations. This is because of the anomalous phase and chemical behavior of water in that…

Part 1: Chilled Mirror Hygrometry (CMH) Of all the instrumental methods for measuring the water vapor content of gases, chilled mirror hygrometry (CMH) is one of the most useful owing to its inherent accuracy, unparalleled dynamic range, ease of…
