Walk-sample stability chamber

Walk-sample stability chamber


Walk-sample stability chamber can be placed a large number of testing sample to reliability tests at the same time, in order to reduce the overall test time of a single product, or the product of temperature and humidity stress screening (ESS), and requires a large space of dynamic tests, as well as bulky products are applicable for this device.
