408L Programmable Environmental Temperature Humidity Chamber 20-98%RH
408L Programmable Temperature Humidity Environmental Test Chamber For Electronics
Programmable temperature humidity environmental test chamber generally have viewports or video feeds to allow for visual inspection of the sample during the test. Reach-in chambers provide an opening that technicians may use to handle test samples. Programmable temperature humidity environmental test chamber providing interior visual lighting must take into account the heat generated and compensate accordingly.
