Hydrophilic membrane-based humidity control
Journal of Membrane Science, 1998A dehumidification system for low gravity plant growth experiments requires the generation of no free-liquid condensate and the recovery of water for reuse. In the systems discussed in this paper, the membrane is a barrier between the humid air phase and a liquid-coolant water phase.

Humidity control tool for neonatal incubator
Medical & Biological Engineering & Computing, 1998In the first days of life, the daily evaporative loss from premature neonates can reach up to 20% of body mass. Such loss can be reduced by increasing the air humidity inside the incubator. Neither passive humidification nor open loop systems allow high humidity rates to be maintained or easily controlled: at 34 degrees C, the maximum levels vary with ...

Controlled humidity gas circulators
Review of Scientific Instruments, 1981A programmable circulator capable of regulating the humidity of a gas stream over a wide range of humidity is described. An optical dew-point hygrometer is used as a feedback element to control the addition or removal of water vapor. Typical regulation of the gas is to a dew-point temperature of ±0.2 °C and to an accuracy limited by the dew-point ...
