Overview

Purpose & Application

The ENV-03-2 humidity cycling chamber executes the full range of standard cyclic damp heat tests including IS 9000-V Section 1/2, IS 9000-VI composite, JSS 55555 Test 17 and MIL-STD-810 cycles B1, B2 and B3. Auto programming controls cycle profile and duration. Single chamber method preferred over dual-chamber for most procedures.
