Three Zone Thermal Shock Test Chamber

Hot, cold and ambient zones in one chamber for full thermal shock profile execution including dwell at room temperature. Specimen remains stationary while air is switched.

Hot +200 / Cold -73 / Ambient Stationary specimen <10 s transition
Three Zone Thermal Shock

Purpose & Application

The ENV-04-2 three-zone thermal shock chamber holds specimens stationary in a single test compartment while pre-conditioned hot, cold and ambient air streams are sequentially diverted into the workspace. This eliminates mechanical specimen transfer and gives the highest test throughput for IEC 60068-2-14 Test Nb and MIL-STD-810 Method 503 thermal shock procedures.
