LW-9022-RT Natural Convection and Constant Temperature Chamber

LW-9022 series generate natural convection condition with accurate temperature control and good temperature uniformity. This mechanism can provide windless phenomenon to convect air simply by temperature gradients. Thus, be able to simulate authentic environments and know real heat transfer performance, including strict environmental factors. These chambers are available in different sizes. All different sizes of chambers can be applied to various kinds of thermal management and cooling issues. Programmable temperature and relative humidity (RH%) control are also available.
