Weather Simulation Chamber

Custom Product

Reproducing various environmental factors

The environmental conditions required by weather simulation chambers vary depending on the research objective and whether the subjects of research are humans, animals, plants, or industrial products. The ESPEC Weather Simulation Chamber can be used to reproduce one or a combination of weather environmental factors, including temperature, humidity, air pressure, rain, fog, snow, sunlight, wind, and air composition. In addition to normal environments, this system can create the optimal weather environment for the research objective and subject, whether it is scorching desert, a frigid South Pole, underwater, high altitude, or stratosphere environment.
