Overview

Purpose & Application

The ENV-02-2 cycling chamber executes complex temperature-humidity profiles such as IS 9000-V damp heat cyclic, IS 9000-VI composite cyclic, JSS 55555 Test 17 and MIL-STD-810 cycles B1/B2/B3. Average or linear ramp rates between 1 and 10 degC/min are user-selectable. Eurotherm 2604 or PLC-HMI program control supports unlimited multi-segment recipes.
